Hi Alberto, You may want to talk with the developer of the VideoCapture module software. I don't know what's going on here. Testing this is also complicated because I don't have a webcam or Windows. Wait, let's back up a moment. You mentioned earlier that: For those who doesn't know what is it its a program that captures images from your USB WebCAM and saves them to send via FTP. Does this mean then that you already have a program that saves webcam images to disk? If so, then if we know what graphical format they are, then perhaps we might be able to use PIL to convert them into a format that your favorite GUI toolkit can display. PIL can talk with different graphical formats: http://www.pythonware.com/products/pil/ Tkinter integrates with this: http://effbot.org/zone/tkinter-plot.htm And wxpython + PIL also appears to work: http://wiki.wxpython.org/index.cgi/WorkingWithImages ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor

In Python, as in other modern languages, functions are first-class objects. In particular, you can pass functions as arguments to other functions, or return functions from other functions. I like examples: def add(x, y): ... return x + y ... f = add # Notice the lack of brackets after 'add' f(3, 5) 8 f(9, 12) 21 In this case, all I've done is assigned to f the function 'add'. This means that f is now a function, and I can call it, even though I never did 'def f(x, y)' anywhere. def square(x): ... return x*x ... range(10) [0, 1, 2, 3, 4, 5, 6, 7, 8, 9] map(square, range(10)) [0, 1, 4, 9, 16, 25, 36, 49, 64, 81] The 'map' builtin function takes two arguments: a function and a list. It makes a new list by applying the function to each element of the old list. ie: This is an example of passing a functino as an argument. Finally: def makeAdder(x): ... def add(y): ... return x + y ... return add ... f = makeAdder(5) f(3) 8 f(8) 13 'def add(y)' defines a function of one argument, which adds that argument to x, and returns the result. What is x? Well, x is a variable in the scope of makeAdder(); it gets bound to the argument you pass. In my example, x was bound to 5. So, effectively, we have created a new function by: 'def add(y): return 5 + y', and then returned that function to f. We can now call f and see the result. HTH! -- John. [ps: sorry for the troll..

Hi Alberto,
I haven't tested your code, but if I understand you correctly, the problem
is that the list is not automatically scrolled when you select a new item
with
the Up and Down keys (right?).
Maybe it's the easiest to add a line like this to your _select1() and
_select2() methods:
l.see(int(l.curselection()[0]))
where l is the first of the listboxes; this should make sure the selected
item is visible
(at least if you use selectmode=SINGLE). If keeping all lists in sync
works, this
should be enough to scroll all other lists, too (like I said, untested
though).
I hope this helps

Re: [Tutor] Hy, I'm a n00b to Python, have some questions
Hey Alex First of all welcome I've been programming in Python for almost 1 year now and I think I can answer two of your questions 1. Is there any decent forum were people are talking in python ? You found one of them, here you have people willing to help each others at no cost. Send an email with your problem and someone here will answer 2. what about speed ? (any beginners question I suppose). Is it something to be concerned about ? Does anyone know how it compares to PHP ? (for Java I allready know) I have no experience in web Python but I do have experience with PHP, JavaScript and ASP.NET and I have to tell you: you can't compare PHP with JavaScript, PHP is server-side and JavaScript is Client-side so the speed is irrelevant because they are two different things. You can compare PHP with ASP. About Python I'm not sure if this is a server or client-side. This is the first thing I would ask. 3. I want any usefull resources you can provide me with You may want to invest in some books. Try searching in Amazon. I have one very practical called Python: Developing Applicattions In fact this is a database book, but the aim is Python on web pages with databases The autor is Sonu Mangla Best Regards Alberto From: Alex Nedelcu [EMAIL PROTECTED] Reply-To: Alex Nedelcu [EMAIL PROTECTED] To: tutor@python.org Subject: [Tutor] Hy, I'm a n00b to Python, have some questions Date: Mon, 18 Jul 2005 16:17:11 +0300 Hy all, I am a Java/PHP programmer.

[Tutor] Scrolling multilistbox help
Hey tutors
I'm using the Multilistbox class and I noticed that it only handles the
mouse scroll and the scrollbar to go down or up.I succesfully implemented
the sort function that came with the class
I also added code to handle the up and down arrow keys and it goes down all
right but only select the item and it doesn't scroll down or up
How can make it go up or down?
I'm sendind the class here:

Re: [Tutor] This should be easy
Hey
Your problem is in the database
I'm surprised how MySQL let you put a space in a field
In MySQL you can't have spaces, as far as I know
Try renaming the field by enteriig to the console and making the alter table
sentence and put Site_Name instead of Site Name. Then make the query again
and see what happens
mysql create table d(autoinc int(4) primary key,Site Name varchar(30));
ERROR 1064: You have an error in your SQL syntax. Check the manual that
corresponds to your MySQL server version for the right syntax to use near
'Name varchar(30))'
This is the error I get from MySQL Server when I try to create a field with
a space and check the solution:
mysql create table d(autoinc int(4) primary key,Site_Name varchar(30));
Query OK, 0 rows affected (0.14 sec)
This should fix your problem.

the autoinc field isn't really an auto-increment field, its an int.
That is left over from the migration from Access.
there are other fields in the table but all can be null.
this line works fine though
cursor.execute(INSERT INTO History (autoinc) VALUES (12);)
this line does not
cursor.execute(INSERT INTO History (Site Name) VALUES ('test');)
can you not have spaces in a field name ? is the quotes gone awry?
dont know what to do next.
please help !

Re: [Tutor] py2exe
Hey all
I had some problems with this module too but I aas able with your help to
make a script that works
Here it is:
from distutils.core import setup
import py2exe, sys, os
sys.argv.append('py2exe')
##setup(
##windows = [{'script': NovusExtension.pyw}],
##)
setup(
console = [{'script': front-end.py}],
)
The commented part is for GUI scripts (Graphic User Interface)
The uncommented part is for CLI scripts (Command Line Interface)
This works 100% sure. I use this piece in all my scripts to make them
executable over Windows. Never tried with pygame though but I think it is
the same. The script doesn't need to be run from command line, but if you
want to see if there is some error, you'll have to (not mandatory I think
you could add a try statement to the code)
If you have Pmw, then you have to freeze Pmw first. IIf this is the case
reply to me, there is a case opened for that and I'll be glad to forward the
answer
Best Regards to all

-O : optimize generated bytecode (a tad; also PYTHONOPTIMIZE=x)
-OO: remove doc-strings in addition to the -O optimizations
optimize=2 means py2exe will optimize the bytecode and remove doc strings;
this
is probably OK since you're not going to be running the debugger on your
finished executable.
and I'm not sure if I put in all of the module names it will need
specified, but it looks as if its supposed to give me an error if it
can't find them).
py2exe will search for all the modules it thinks it needs, but sometimes it
will
miss some. Generally, the best way to find out if it missed anything is to
run
your executable and see if it crashes :-)
But then the tutorial says simply run this script
and it will do all the work.
You need to run it from the command line: python setup.py py2exe

[Tutor] MineSweeper
Hey Tutors I have a question I want to make a minesweeper (just for practice) but I don't what can I use to make the GUI I was thinking about buttons (click event you know) and change the background image on change Maybe there's another widget to use My doubt is that I want to be able to allow the user to put how many bombs they want and how any spaces (how big is the board) so I will have to create buttons dinamically, but in doing this the reference to the buttons will be lost How do I know which button did I click when all buttons have the same name? Does this make sense? I recall in VB.6.0 the control matrix but I never knew how to use it Any help?

Hi, The 'nohup' command is to make sure that the child process sticks around after the parent (and grandparents) have died. When a process creates a child, the child is tied to the parent and when the parent exits, all the child processes get sent a specific signal (with os.kill()) telling them that the parent has died. The default procedure when they receive this signal is to exit. A little history: back in the days of only modems, you would dial into a UNIX mainframe from a terminal and if the modem disconnected, the system (or you) would not want all your processes hanging around afterward. For this reason, the UNIX system would send a hangup signal (SIGHUP) to the login shell and all its child processes. Shells added a nohup (no hangup) command so certain processes could survive if the user wanted. When you say nohup it tells the process to ignore the default procedure and to ignore the SIGHUP (hangup signal). It does not put the process in the background so you still need the and it does not change stdout and stderr (that is why I put those in my e-mail too). In python, you would just say: os.system(nohup python2.2 /root/levantamuertos.py /dev/null 21 ) This should handle most headaches. The headaches that I mentioned are going to be very subtle. 1. One is that sometimes developers have changed shells without telling users. It has happened in the past that has had an implicit nohup in one version of a shell and in the next release, the implict nohup is no longer there. It is better to be explicit and clear... it also helps readability. 2. A second headache comes from the output streams (stdout and stderr). You want to be running a number of these levantamuertos.pyprocess at the same time. Did you know that the output of your cron job is captured and e-mailed to you? And by default, the output of child processes (levantamuertos.py) would be the same as cron job, usually only on error? So you might get a lot of mixed output from the different levantamuertos.py processes running at the same time. If you send all the output to /dev/null. Or to specific log files (based on PID), then you may not have this headache. I hope this helps and wasn't too pedantic. I get that way sometimes. -Arcege -- There's so many different worlds, So many different suns.

[Tutor] Process problem
Hey all
I have a problem with a program
You see, I have a python script made in Python 2.2 that runs every 15
minutes on Linux Red Hat 9.0
This program (which code is attached below) named levantamuertos.py (spanish
for death weakener) has to check in a database if the pids stored are
running (note that it will be more than one pid) and if they are not it has
to start again the process and it will store the new pid on the database
The problem is that when I call it it runs and weaks all dead process but
when it dies, he takes all his sons with him.
How can I make that the cotascamon.py keep running although
levantamuertos.py die?

Re: [Tutor] Process problem
Hey
Let me make you understand
I need that levantamuertos.py run cotascamon.py (every script with it
differents arguments that are passed) and then die letting the cotascamon.py
scripts running independently
Now, I don't know if my code is right, and thinking now you're right,
levantamuertos.py waits until cotascamon.py finish.
What can I do since cotascamon will never die (and it doesn't have to die)?
Maybe a different approach will be the solution but I can't find a way to do
it

Hi Alberto,
Mmm I'm not sure if I get this all right. Why do you want to keep
cotascamon running after levantamuertos dies?? If you're using system(),
levantamuertos is waiting for cotascamon to finish completion before it
continues running, there should be no point where levantamuertos *runs*
while cotascamon also does (levantamuertos is sleeping)
One advice though: it is easier and more elegant if you, instead of
parsing the output of ps for a single process, you send it signal 0.
This will do nothing to the process itself, but will complain with a
traceback (OSError) if the pid does not exist. Like this:
from os import kill
from signals import SIG_DFL
pid = 16
try:
kill(pid, SIG_DFL)
except OSError:
print Process does not exist...
Please note this is untested as I'm os a Windows machine right now =/
Hope it helps,
Hugo

Re: [Tutor] Just a Python formatting question
Kristiano Don't worry about it. I'm sure everyone passed over this before. The identation errors are errors in the tabulation of a line Let's take your code in example number=78 guess=0 while guess != number: guess=input (Guess a number:) if guess number: print Too High elif guess number: print Too low The last line has to belong to the elif clause, right? so if you are working with a single tab or 4 spaces (default identation in Python) that means that for every loop statement, try , functions, classes or any line that ends with :, the next line has to be 4 spaces forward. And all the lines that belong to the statement also. It does not matter if is a nested sequence. Let me lighten you: for i in somelist: do_something do_something_else if x==y: inside the if clause all statements go with 4 spaces after the if line elif xy: the same here You ended an identation when you went back the spaces and typed elif so you don't acumulate the identations, you just keep using 4 spaces after the line with the : so Python knows what's inside and what's outside I hope to be clear, and if you don't understand it (probably because of my English) you can always read in the tutorial or in the Python help Best Regards Alberto print Just right I just can't get it to run and I get some indentation error.

From that point on, any reference to attributes of the Pmw 'module' is handled by the loader. The real Pmw package is stored in sys.modules['_Pmw']. ... Freezing Pmw Since the dynamic loader requires that Pmw be installed at run time, it can not be used when freezing Pmw. In this case, a single module containing all Pmw code is required, which can then be frozen with the rest of the application's modules. The bundlepmw.py script in the Pmw bin directory can be used to create such a file. This script concatenates (almost) all Pmw megawidget files into a single file, Pmw.py, which it writes to the current directory. The script is called like this: bundlepmw.py [-noblt] [-nocolor] /path/to/Pmw/Pmw_X_X_X/lib The last argument should be the path to the lib directory of the required version of Pmw. By default, the Pmw.py file imports the PmwBlt and PmwColor modules and so, to freeze an application using Pmw, you will need to copy the files PmwBlt.py and PmwColor.py to the application directory before freezing. If you are sure that your application does not use any of the Pmw.Blt or Pmw.Color functions, you can use the -noblt or -nocolor options. In this case Pmw.py will be modified so that it does not import these module(s) and so will not need to be included when freezing the application. If your application only uses a few Pmw megawidgets, you can remove the references to the usused ones in the files list in the bundlepmw.py code. To make the change, take a copy of the script and modify it. This will make the Pmw.py file smaller. However, be sure that you do not delete megawidgets that are components or base classes of megawidgets that you use. If you haven't done this, you will need to, otherwise Pmw won't work with py2exe. -- John. ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor Gaucho ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor

[Tutor] Disable menubar
Hey everyone
I've read about menubars and I decided to use the MenuBar from PMW instead
of Tkinter's
The reason is that I couldn't find an example to make a menu with cascade
submenus and another cascade submenu inside the submenu and so on.
Now I want to ask if somebody knows how to accomplish these with Menu from
TKinter?
On the other hand, every button on the menu opens a Toplevel, but I want to
restrict the Toplevels to one of each kind. I was thinking in disable the
menubutton but PMW only has disable_all and I only want to disable the
opened Toplevel. Is there another way to accomplish this using Menu from
TKinter or MenuBar from PMW or any other option?
I'm sending a copy of the code of the menu (If you think you'll need all the
code tell me because is kind of long and has many things that I haven't
tried yet)
Thanks in advanced
Alberto

Re: [Tutor] Disable menubar
YES That's what I was looking for and I will replace it. I don't like to much the MenuBar from Pmw its different and it does not have all the menu attributes that windows menu have (or maybe I don't know how to use it well :D) About disabling the button it would be nice to know if that can be done , although I made some work around and I managed to restrict the Toplevels.

Now I want to ask if somebody knows how to accomplish these with Menu from TKinter? Here is some code: from Tkinter import * tk = Tk() m = Menu(tk) m2 = Menu(m, tearoff=False) m.add_cascade(label='foo', menu=m2) m3 = Menu(m2, tearoff=False) m2.add_cascade(label='bar', menu=m3) m3.add_command(label='One') m3.add_command(label='Two') tk.config(menu=m) Is this what you are after? Check the attachment for what it produces. You could add more menus, eg: m4 = Menu(m3, tearoff=False) m3.add_cascade(label='baz', menu=m4) m4.add_command(label='Three') m4.add_command(label='Four') I think using Tkinter.Menu is better than Pmw, because Tkinter.Menu will use native menu widgets (which means your menu will look the same as other menus in other apps), whereas I think Pmw may do its own thing. -- John. menu.jpg Gaucho ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor

I am trying to make a loginbox for a program, and need to make a somewhat safe passwordroutine.

These lines will create a string: '12c0faae657b3d068c0f19b71f5b43bc' This string will be stored in the file settings.txt Then, I will do the same where the password is entered in a GUI-box. Then I will do the same, and compare. If file.readline == h.hexdigest() the user will be accepted. Is this a good way to do this? And a second question. I have made a tkinter box with two entry-fields. Is there a way to make the letters in the second entrybox appear as as the user types his password? Is there some built in function in the Tkinter Entry that does this?

Re: [Tutor] Troubles with Python modules
First of all, thanks for the corrections I'm assuming that Python 2.2 doesn't have datetime module then??? Is there any way to install it??? My version of Python 2.3.4 is an alternative installation so I know that when I type python with my root account its going to Python 2.2.2 (I'm using the root account) I changed the link though so when I say Python I enter Python 2.3.4 (works and checked) I'm sending the errors MySQLdb gives me when I try to install it. It's hola.txt file I'm doing python setup.py build and inside hola.txt you can see what it says I have installed Linux Red Hat with ALL packages Can I add datetime module to Python 2.2.2 ??

Second the error is the following: Traceback (most recent call last): File /root/cotascamon.py, line 4, in ? import datetime ImportError: No module named datetime I think this module is in Python 2.3. What can I do?? I'll assume for the moment that you are using your root account. Are you sure that your root account is using Python 2.3? It may be possible that the root account has a slightly more restricive PATH than normal user accounts, and that you might be picking up '/usr/bin/python'. Then I have installed Python 2.3.4 in the same Linux but I can't use it because it doesn't recognze the module MySQLdb Here is the error Traceback (most recent call last): File /root/cotascamon.py, line 3, in ? import MySQLdb File /usr/local/lib/python2.3/site-packages/MySQLdb/__init__.py, line 27, in ? import _mysql ImportError: No module named _mysql Different releases of Python will not automatically migrate the old third-party modules. You'll need to reinstall MySQLdb for Python 2.3. MySQLdb can be found here: http://sourceforge.net/projects/mysql-python Let's look at some of the code. def consulta(self,query,args=None): try: self.cursor=self.db.cursor() self.sql=self.cursor.execute(query,args) except: self.cerrar() else: self.cerrar() The consulta() function tries to make sure that the cerrar() method is called, no matter what.

Contacte al administrador.) f.close() This looks like it's trying to do argument parsing, storing state in global variables. You may want to see if you can avoid the globals, and instead just return those three values back to the caller. My nervousness with the globals comes from the requirement that getpath() has to assume that 'ruta' already has some sort of value already. So there's already a dependency that can be more clearly documented by making getpath() take in an initial base path argument: ## def getpath(base_path): ... return (ruta, user, cam) ## But the block above also feels a little awkward because it assumes that any exception that occurs has to be a path problem. That might not necessarily be the case. I'd strongly recommend letting the exception speak for itself. traceback.print_exc() can help: http://www.python.org/doc/lib/module-traceback.html ## try: except: f = open(cotascamonerrors.log, a+) traceback.print_exc(file=f) f.close() ## Up to this point, though, things are pretty ok, with the nice helper functions with clear roles. The large block near the bottom, though, needs work. I'd recommend applying the same helper-function breakup to make the code's intent clearer. For example, here's SQL code that's repeated, a. It should be broken out: try: os.system(cp webcam.jpg grabacion/cam+grupo+.jpg) query=INSERT INTO imagen values (%s,%s,%s,NOW(),NOW(),%s) where CodigoCamara=%s and Usuario=%s grupo1=datetime.datetime.today().strftime(%Y%m%d%H%M) ruta1=ruta+/grabacion/cam+grupo+.jpg args(user,cam,ruta1,grupo1) cur.consulta(query,args) except

time.strptime() can parse the time string to a time tuple, then you can
pull out a tuple of (hours,
minutes) and compare.
import time
time.strptime('10:23', '%H:%M')
(1900, 1, 1, 10, 23, 0, 0, 1, -1)
Here is a helper function that extracts (hours, minutes) from a provided
string, or from the clock
time if no string is given:
def getHoursMinutes(ts=None):
... if ts:
... t = time.strptime(ts, '%H:%M')
... else:
... t = time.localtime()
... return (t.tm_hour, t.tm_min)
...
getHoursMinutes()
(9, 52)
getHoursMinutes('8:34')
(8, 34)
hour1=14:30
hour2=15:30
getHoursMinutes(hour1)
(14, 30)
The values returned from getHoursMinutes() can be compared directly:
getHoursMinutes(hour1) = getHoursMinutes() =
getHoursMinutes(hour2)
False
hour1='8:56'
getHoursMinutes(hour1) = getHoursMinutes() =
getHoursMinutes(hour2)
True

[Tutor] Linux variable to Python
Hey Another problem Here is an example of what I want to do: I run over Linux shell the following command: [EMAIL PROTECTED] root]# fec=cam`date +%Y%m%d%H%M%S`.jpg [EMAIL PROTECTED] root]# echo $fec cam2005051255702.jpg [EMAIL PROTECTED] root]# mv hola.txt grabacion/$fec To explain for those who doesn't know: The first line creates a variable named fec with the value cam(a Linux function returning year month day hour minute second).jpg The second show the value of fec The third moves hola.txt to the directory grabacion and puts the fec value as the new name for the file I need to do this from Python but I'm having problems with the Linux variable I don't get any errors when I execute the commands Here is what I'm doing import os os.system(fec=cam`date +%Y%m%d%H%M%S`.jpg) 0 os.system(echo $fec) 0 os.system(mv hola.txt grabacion/$fec) 0 Then I check for the file and turns out that it moved hola.txt to grabacion with the same name I think that for some extrange way it is not accepting the linux variable I'm using Python 2.2.2 over Red Hat 9.0 Thanks in advanced Alberto ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor

If so, you may want to consider using a regular user account unless you really know what you're doing. Running things as root should never be taken lightly.] You may want to consider using the 'datetime' module for this one. There are portability and security issues that you may not be considering whenever you shell out. If you use Python's Standard Libraries, you can avoid these issues. I think you can avoid using 'date' by taking advantage of datetime.datetime.strftime(): ## import datetime datetime.datetime.today().strftime(%Y%m%d%H%M%S) '20050513135531' ## This is portable on any system that supports the Python Standard Library. The problems you are running into with os.system() are related to those that other people have been asking about this week. It's sorta funny how these questions come in streaks. *grin* For more information on driving external processes with Python, you may want to look at the messages on Pipe variable to external command that Jeffrey was asking about yesterday: http://mail.python.org/pipermail/tutor/2005-May/038341.html http://mail.python.org/pipermail/tutor/2005-May/038343.html I hope this helps! ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor

Re: [Tutor] zip question
The problem is that you have to get the content before you can get the filename or comment of the files. You have to do something like this import zipfile file=zipfile.ZipFile(yourfile.zip) f=file.getinfo(name_of_the_file_inside_yourfile.zip) And then you can take the comments and filenames you want with f.comment f.filename Copy and paste without parenthesis. The getinfo part, You have to get the name of the files inside.

Re: [Tutor] Problem with threading
Hi I took a look at the code and now I'm confused I'll use CRON and I will make a python script that take parameters (username) and work only for that user but the script will never finish ÇThe FTP connection that starts the camera never ends unless I shutdown my server. Now I'm thinking that CRON will start my script only once and I will make a script that check for the record time of the user and insert all the photos that are in the record time but is there a quick to insert the filename with path to the database I'll have all the photos in one directory and I want to check all directory quickly cause after it finish it will start again and again and again and again and again and again.i think you get the picture Imagine 40 users running all at the same time. I have to ask, does the machine will overhead with this process???Does CRON make my script run as a daemon or should I insert the daemon code you gave me: http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/278731 What is the difference in running with CRON without the daemon code with running with the daemon code??

But how about writing a program that just continues to run as a daemon service in the background?

Hey all This is the program I need to do and I haven't been able to figure out From a web page (PHP), I'm creating users and an IP Camera that sends me photos all the time.

Here, 'application_wrapper' is a simple wrapper that itself calls the real 'application_I-build' program with the right command line arguments, for each user in the configuration_file.txt.

[Tutor] Help with daemon
Hi everyone Again disturbing the peace of the TUTOR :D I'm making an application to check every few seconds for photos uploaded via ftp The users will program their upload time via web page (made in php). The time is saved in a MySQL database so I will check for all the created users if they are in record time. I'm applying a security politic that when the users are in record time then the ftp will let them write and erase, but when they aren't the ftp only will let them read. Here is my problem. Imagine 100 users and lets say that User A connects at 9:00 and User B will connect at 9:10. When I first check at 9:00 User A is in record time so he can send photos but User B does not. The program will have to check for all 100 users and will hardly reach for another check at 9:10 and it will loss transfer time. The OS is linux and the version of Python is 2.2.3. The question is, how can I make the application to manage a process for each user the database find, so only one process will attend one user and I think it will be fast enough to cover the record time. I don't know if my approach is right, I'm new with multithreading and I will appreciate the help. I'm gonna give you an example: The program will check for new users and to check record time every 10 seconds. But first the program will have to finish the checking process that started before so it won't be 10 seconds right? Unless I have one process for each user to check the database at the same time is checking other users Thanks for the help and I hope this is clear (and not long) enough for you to help me Regards Alberto ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor

You may think that those error messages are mostly the same, but we REALLY wanted to see that for ourselves. Please don't interpret error messages for us: please let us make that judgement for ourselves. Again, I have to stress that we really like seeing good error messages. This may sound weird to you, but the error message that comes out is usually much more descriptive than you might realize. the final error says error: mysql ended exit with status 1 Right, but now we can't tell if it was a problem during compilation, or linking, or any other kind of possibility. In your next email, you mentioned: The exact error is the following: Error: compiled 'gcc' failed with exit status 1 which is equally uninformative. All errors will eventually end up with saying something like something bad happened. But what we need is first cause: at what point do things start to go horribly wrong? And that's what the error log tells us. If you had shown us the whole transcript of the error log, we'd have a much better chance to give you exact answers on, at what stage, the problem starts to emerge. With what you're giving us now, we have no clue. If the error log is really that long, then zip it up, and put it as an attachment. But don't just omit it altogether.

If you right click the file, go to edit in IDLE, and hit F5 to run it, the crash does NOT happen. I'm not sure why (but this is also why my debugging program won't tell me what's wrong). In fact, I wish the debugger *would* give me something, because then I'd have a specific error, which would make researching the program on google or in forum archives much easier!

I sent answers to the general questions to the tutor list, so that hopefully the extra clarification might help someone else answer (I havent had much luck with this thread, unfortunately). But I wanted to reply to you personally to send a copy of the game. It's a mod of a game from pygame, but I've added a lot of stuff to it. I'll send it as a zip file with two different play files - run the one simply called play to test out the game without the crash (oh, a side-note: the enemy ships will change graphics on levels 2 and 3, but they're not pretty - i just put those graphics in there as a place holder until i make their prettier replacements). Anyway, the play file called copy of play wscorelist2 is the copy with the scorelist that is crashing. If you just want to see the *code* you can look at either of those two files, but I thought you might want to play the actual game so I'm sending it all. Have fun :) Any comments/ideas/suggestions are very welcomed!! I'm having a couple friends test it out. But since I'm new I might not be able to take ALL of the suggestions before I have to have the game done next week, ha ha. Anyway thanks so much for replying, and for any help or suggestions you might have about the crash. ~Denise P.S. if you dont have them, you'll need pygame and the livewires module, available at http://www.livewires.org.uk/python/lwpackage.html .

For information on how to do send plain text emails, see: http://www.expita.com/nomime.html My best guess so far is that the Tcl/Tk development support on your system is spotty: depending on your Linux distribution, you may need to install additional packages so that Python can find the Tcl/Tk stuff. Unfortunately, this is distribution specific, so there's not set way for us to show how to fix this. I'm guessing that you have some sort of Linux distribution. Unfortunately, I'm not familiar with Release 3 of any distribution, so we'll need more information. Do you mind doing this for us? Try executing: ### import sys print sys.plaform print sys.version ### Here's what shows up on one of my systems: ### import sys print sys.platform darwin print sys.version 2.3 (#1, Sep 13 2003, 00:49:11) [GCC 3.3 20030304 (Apple Computer, Inc. build 1495)] ### Show us what happens when you execute those commands, and that'll give us a better idea what Linux distribution you're running.

I tested and
the Option 1 gives the message of "That has been difficult" stuff when you pass the 3 errors and still ask you for password. The option 2 loops 3 times unless you put unicorn or whatever is the password and at the third time it gives the message and then increment the current_count once more to take you out of the while loop Test it and let me know how it went, and also if I have a few problems with my writing please let me know as I will try to correct them You are absolutely right that your `Option 2' code does exit the loop. I somehow missed that the while condition had an `and' in it :-[ My apologies. Your second post said you intended the final if clause to be: if password=="unicorn": # etc I've changed it to if password != "unicorn": #
etc and get what I would think is correct behaviour. So, it now reads: password = None # necessary pre-setting of names current_count = 0 count = 3 while password != "unicorn" and current_count = count: if current_count count: password=raw_input("Password:") current_count=current_count+1 else: current_count=current_count+1 print "That must have been complicated" if password!="unicorn": print "Try again Later" else: print "Welcome in" I would suggest that it be done like this, though: # pre-sets as before go here while password != "unicorn": if current_count count: password = raw_input("Password:") if password=='unicorn': print 'Welcome in' else: print "That must have been complicated" print "Try again Later"
break current_count += 1 This pushes all of the actions consequent on the password into the password fetching loop and uses just a single incrementing line. Anyway, once again, sorry for misreading and mis-correcting you. Best, Brian vdB

At the end of this, outFile is a file-like object whose content should be that JPEG image. db=MySQLdb.connect(connection string) cursor=db.cursor()
cursor.execute("insert into image values('',%s)",outfile) This last statement is problematic. Remember: outFile is a StringIO object, not a string. A StringIO object responds to a str() call with the following: ## from StringIO import StringIO s = StringIO("hello world") s StringIO.StringIO instance at 0x41d00 str(s) 'StringIO.StringIO instance at 0x41d00' ##So we can't use the default.

Have you checked to see what's stored in your database after you've done that? What Danny said was: Here, we use StringIO to use an in-memory file-like object: http://www.python.org/doc/lib/module-StringIO.html and we can use getvalue() to get at the binary bytes that you'll
probably want to store into your database. Depending on just how you're getting the data for your images, you may want to go through a StringIO object or you may be able to just work with the bytes that are in the file. But it's pretty common that it's not a very good idea to store image data in a database. If your images are pretty small and your database has a "BLOB" (binary large object) type, you may have some luck. If either of those isn't the case, the overhead of getting your images into and out of the database may overwhelm your machine. You might want to consider storing your image files semi-randomly in a directory hierarchy and recording in your database only the path to the file. If you have only a few hundred or a few thousand images, a single directory may be sufficient. If you have many more of them than
that, you may want to split them up according to some rule that results in approximately equal numbers going in different directories.cursor.execute("select * from image") res=cursor.fetchall() Now I have the binary string in res[1] but when I try to open it it gives me an error Here's where you may want a StringIO object. If whatever you're giving the image to expects it in a file rather than a string, you could do somwthing like:s=StringIO.StringIO() s.write(res[1]) s.seek(0) and then give the variable s to whatever wants to read the file.

Re: [Tutor] str.split and quotes
Thanks Kent but now I need you to explain me the code :( To give you a graphic example how can make this function to run every 5 seconds def foo(): print "Hello world!"

Re: [Tutor] str.split and quotes
Hey Kristian, thanks for the reply The problem to use sleep is that all widgets gets locked up and they doesn't refresh themselves I just made that example so anyone can explain the code Kent posted earlier In my real application is a Tkinter GUI so I should not use sleep Thanks anyway Regards AlbertoFrom: Kristian Zoerhoff [EMAIL PROTECTED] Reply-To: Kristian Zoerhoff [EMAIL PROTECTED] To: Alberto Troiano [EMAIL PROTECTED] CC: [EMAIL PROTECTED], tutor@python.org Subject: Re: [Tutor] str.split and quotes Date: Mon, 11 Apr 2005 11:03:13 -0500 On Apr 11, 2005 11:00 AM, Alberto Troiano [EMAIL PROTECTED] wrote: To give you a graphic example how can make this function to run every 5 seconds def foo(): print "Hello world!"I'm not Kent, but I play him on TV ;-) import time def foo(): print "Hello world!" while true: foo() time.sleep(5) -- Kristian kristian.zoerhoff(AT)gmail.com zoerhoff(AT)freeshell.org ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
