Re: [Tutor] My First Program
Hi! My first ever program that I've created is a simple game called State Capitals. It's straight forward; 5 simple questions about state capitals ina non-GUI format. Can someone look over my code and offer tips, suggestions,criticism? Also, I'd like to be able to end the program if the user misses 3 questions (i.e., kick them out after the 3rd wrong answer). How can I dothis? Thanks!print \nState Capitals! Answer a or b to the following questions.\nquestion = raw_input(Question 1 - What is the capital of NC, a: Raleigh or b: Atlanta? )if question == a:print Yes\nelse:print WRONG\nquestion = raw_input(Question 2 - What is the capital of SC, a: Greenville or b: Columbia? )if question == b:print Yes\nelse:print WRONG\nquestion = raw_input(Question 3 - What is the capital of NY, a: Albany or b: Buffalo?)if question == a:print Yes\nelse:print WRONG\nquestion = raw_input(Question 4 - What is the capital of OH, a: Cleveland or b: Columbus? )if question == b:print Yes\nelse:print WRONG\nquestion = raw_input(Question 5 - What is the capital of TX, a: Houston or b: Austin? )if question == b:print Yes\nelse:print WRONG\n Hi! Glad you picked up Python. You'll probably enjoy it. This might be over your head, but I'd use functions for your Yes and WRONG: def yes(): print Yes\n def WRONG(): print WRONG\n # Now for the sample code: question = raw_input(Question 4 - What is the capital of OH, a: Cleveland or b: Columbus? ) if question == b: yes() else: WRONG() Hope this helps.

Re: [Tutor] Timer
Sorry, this is a little console project to tell me when there new headlines on slashdot.org using their rss file. All it does is see if there's something different and if there is it will tell you. Here's my timer: while True: if count 1800: break time.sleep(1) count += 1 Or should I just do: time.sleep(1800)? A little context would be helpful. If you are writing a standalone appthat just needs to wait 30 minutes, then do something, use time.sleep().If the program needs to be able to do something else at the same time as the timer is running, you will have to put the sleep() call in aseparate thread. threading.Timer will do this for you, see this recipefor an example of its use: http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/440476If you are running in a GUI app, the GUI toolkit may have a timer youcan use, for example in Tkinter widgets have an after() method thatschedules a callback for a future time; wxPython has wx.FutureCall.http://www.pythonware.com/library/tkinter/introduction/x9507-alarm-handlers-and-other.htm http://www.wxpython.org/docs/api/wx.FutureCall-class.htmlKent-- There are 10 different types of people in the world.Those who understand binary and those who don't. ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor

[Tutor] Module Thread
I'm back to my IRC client. I accidentally found the thread module in the Python 2.3 documentation while looking at the time module. What I can't get ideas or hints from the documentation is: What will i do to receive and send at the same time via console? or: Should I forget the idea of a console and start learning GUI which will do this for me. and lastly: Should I have a program that handles all the sending and receiving and puts it into a file and have to sub programs one that will write to the file that the main program will read and send and one that just reads the file which is received data.

Re: [Tutor] slide show won't display the images in right order
Hi, Thank you all for your help. I must say that the python mailing list is the most helpfull of any place I've ever asked for help on. A close second comes linuxquestions.org. Somehow sort() got passed me in the Python Documentation and sort() has fixed all my problems. EDIT Sort still didn't work but I found another fault: the direction variable. I took it out and had x += 1 and x += -1 to view the pictures ShowImg(files[x]) (x is the location of the image in the list 0, 4, 100, etc). It works great now.

Hi Michael, You're explanation helped a lot, however, I'm really not good at gui programming and the irc client was supposed to be a console application, but: Would it be hard to just have a send texbox and receive read-only text box?

Ok. Thanks for the heads up.
As to your printing problem, I'm not sure if you're referring to -
print msg[print_msg]
Oh, sorry. I'm refering to the print msg[print_msg]
And I'm not sure if you want it to print without an additional newline, or
with a newline.
Well every word is on it's own new line (I get a huge message from the
IRC server) and I'd like a word wrap or something to fix that.
#Incidentally, it's a bit simpler to maintain this kinda loop
#instead of a while loop.
for item in msg:
item.rstrip() #Will strip whitespace (\t\r\n etc.) by default
print item
Ah. Thanks
If you're wanting to print without the newline that print adds, why not do a
join like this one? message = ' '.join(msg[3:])
print ' '.join(msg) ?
Thanks again. This is proving very usefull.
What output you're expecting

and possible word wrapping.

I edited the code from a Python Cookbook recipe.
I may toddle off and check
out that RFC.
Yes. Some people on a forum that I hang oput with suggested a chat
room. A freind of mine suggested IRC and python. He's doing the server

Re: [Tutor] IP Address from Python module?
Danny Yoo wrote:
Hi Joe,
That actually sounds right in a sense. Any internet address with
'192.168.x.x' is a "local" IP address, and is commonly allocated to folks
on an internal network. For the really dull details about this, see RFC
1918 on "Private Address Space":
http://www.faqs.org/rfcs/rfc1918.html
So anything with 192.168.x.x is a private, internal address. In the
context of the Internet, it's sorta useless, since it's not an address
that one can use to connect to an external machine outside of the local
area network.
In fact, Brian Hammon's comment in:
http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/335890
does mention that if you're behind a router, then the router itself sets
up a small private network, which may explain why you may be seeing
'192.168.x.x' as an address.
The second comment on the cookbook page shows an alternative technique
that should be more robust: use http://checkip.dyndns.org.
My internet IP should be IPv6 and I don't think it changes...
Are you sure about that? IPv6 has not been widely deployed yet; most
folks still connect to the internet through the IPv4 protocol.
On the off-chance that you ARE on IPv6, see the getaddrinfo() function,
which should accomodate:
http://www.python.org/doc/lib/module-socket.html#l2h-2592
For example:
##
import socket
socket.getaddrinfo('hkn.eecs.berkeley.edu', 80)
[(2, 1, 6, '', ('128.32.47.228', 80)),
(2, 2, 17, '', ('128.32.47.228', 80))]
##
Good luck to you!
Thank you. And thank you for the links. Well I remember something on a
game I played and it had a IPv6 address (refering to my computer while
o nthe internet).. of course I bought my computer parts in October 2004
so there could be a good chance that I do not have IPv6... either way,
thanks. :-)
Oh and I don't have a router... just a good old-fashioned CAT5 hub.

Hi. I have 7.8 GB of music (1808 songs) and I use XMMS to play them. However I can't find some songs.

#become a server socket
serversocket.listen(5)
while 1:
#accept connections from outside

Re: [Tutor] Tkinter Q's
Hi,
what's the **kw stand for, used for? What does it mean?
Some comments ---
You create a Frame, but you never use it.
You've put a whole lot of code in a class, but it's not in a class method.
This
is kinda missing the point of using classes in the first place (and it just
flat-out wouldn't work in the majority of OO languages).
Here's what I would do:
class Main(Frame):
def __init__(self, master=None, **kw):
Frame.__init__(self, master, **kw)
showquote = Label(self, text=random.choice(quotes.quote))
showquote.pack()
# etc
if __name__ == '__main__':
root = Tk()
main = Main(root)
main.pack(fill=BOTH, expand=True)
root.mainloop()
###
Do you see what I am doing there, and why it is different from your approach?
Uh, not really, no. I'm very new to GUI. So you're saying that If I make the
class actually do something (I edited and example in:
An into to Tkinter, Fredrik Lundh).
Once you've got a label, you can change its text attribute by using its
.config() method.
So, you could do something like this:
# ...
showquote = Label(self, text=random.choice(quotes.quote))
showquote.pack()
def changeQuote():
currQuote = showquote.cget('config') # Get the current quote
newQuote = random.choice(quotes.quote)
while newQuote == currQuote: # Make sure the new quote differs
newQuote = random.choice(quotes.quote)
showquote.config(text=newQuote)
Button(self, text='Show another quote', command=changeQuote).pack()
Aaag. I'm confused... I just tried you changeQuote example with out the above
stuff... didn't work. My error message:
AttributeError: 'NoneType' object has no attribute 'config'
so I edited it a little, still didn't work (same error). I tried the class
Main(Frame) and didn't get it to work either. Do you think you could make it a
little bit simpler? If you can't that's ok, I'll try to study it more.

Re: [Tutor] YATENJoe
If you intend to make a text
editor (something which allows the user to browse
through the text and manipulate it at will) using just raw_input and
print, I
think you've set yourself an impossible task. For a console editor you
should
probably look at curses
(http://www.amk.ca/python/howto/curses/)
- which don't
work on Windows, so you'll probably need this:
http://adamv.com/dev/python/curses/
(but according to the site it's incomplete).
Ok.
lines = []
while True:
lines.append(raw_input(''))
(But that offers no way to e.g. save and continue.)
Ok again.
Text editors are IMO not applications suitable for learning vanilla Python, or
OOP for that matter. Text editors are used as example applications in the RAD
IDE world (VB, Delphi and such) because in those environments a text editor is
literally three clicks away (click on memo component, click on form, click on
run). Vanilla Python has no GUI, so no memo component - hence my recommendation
for Tkinter or wxPython. PythonCard and Boa provide an experience somewhat
similar to commercial RAD IDE's if that's what you're looking for.
I got my idea from looking at Nano, Vi, Joe and a few other UNIX text editors. Nano and Joe are console programs. That's why I thought I would try a console ed. in Python.
Having one function for each line is a bad idea whether you code it by hand or
automatically
Ah.
A function implements certain behavior. Having the same behavior (raw_input)
implemented separately for each line is an extremely wasteful way of
programming.
Is there a way of telling Python to make a new line after you press Enter (return)?
I would suggest that you learn a bit more about Python's facilities before
embarking on an ambitious project :) - you won't get very far without knowing
how to use lists and dictionaries.
So that's one of the ways Dicts, and lists are used for? I never could fully grasp their use.
Thanks,
JQ

[Tutor] YATENJoe
YATENJoe (Yet Another Text Editor, Named Joe) First off, If this isn't the right place to ask, tell me so. That way I won't make this mistake again :-) I want to make a text editor. I know that there are hundreds out there, but practice makes perfect, and I need the practice. My problem is that I have no idea how to make one. I've tried a little already by defining line functions: def line1(): l1 = raw_input() def line2(): l2 = raw_input() line1() line2() Of course, this only allows for 2 lines. What's the trick to an infinite number of lines? Event driven programming is a must, obviously. How can I use 'Ctrl' + 'Q' to quit while still being able to type: Press 'Ctrl' + 'Q' to quit YATENJoe? I'm still a newbie to python (actually OOP programming in general!) so I can't have a lot of complicated stuff thrown in my face. I'd like it to not be platform specific, but if it has to be OS bound to be simple, then that's fine. I thought of a function that would define a function for me. Is this possible? If it is how would I do it? If it possible, here's my idea: def makefunc(): # This is where it defines a function. If line1 = full then # make a new line adding 1 integer do separate it from the first. def l1(): l1 = raw_input() line1 = full l1() makefunc() One other thing, is there a way to call a function that is inside a function? 'Cause makefunc().l1() doesn't work. Thanks in advance, JQ PS: FYI I use Windows XP Pro and Linux PPS.

[Tutor] Re: Installation Routines (Joseph Quigley) (Jay Loden)
Interesting. So several distros use rpms? I though only red hat used 'em. Rpm does in fact have dependency resolution, and rpm-based distributions use a package manager that can download the dependencies and install them for you - urpmi on mandrake, yum or apt4rpm on Fedora and Redhat, Yast on Suse I've used all of these, they are all rpm based, and they all install dependencies. If you use the raw rpm command, even that will tell you missing dependecy foo. That being said, apt-get on debian is still my favorite (for sheer number of available packages), but urpmi on mandrake or Yast on Suse are quite excellent. -Jay On Wednesday 20 April 2005 04:17 pm, Max Noel wrote: emerge and apt-get come to mind. rpm is inferior (no dependency resolution) but still does a good job, and I hear autopackage isn't bad. ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor

Re: [Tutor] Installation Routines (Joseph Quigley)
Its not hard, but its not easy either to do it right. And given the profusion of installers already available ranging from free to expensive there really is little point in writing something that probably won't be as good as the already available alternative. Remember user expectation, if you write an installer you should also provide an uninstaller, and link it to the Control Panel Add/Remove applet. Its no coincidence that python uses a commercial (Wise) installer for the Windows distro... This isn't a waste of your or my time is it? No, its a valid question even if the answer is that its probably a bad idea! Alan G. My point is for practice and knowledge. Sure, I have Setup 2 Go (the paid version) and Install Creator (not paid) Then again, how many free installers are there for linux? I must get a book on Windows before I make a nice installer.

Re: [Tutor] New to programming question (Ben M.) (Joseph Q.)
if letter == 'O':
print letter + 'u' + suffix
elif 'Q':
print letter + 'u' + suffic
else:
print letter + suffix
Do you see? The == binds more tightly than the or. And, in python, 'Q' is
considered True for the purposes of tests.
So this is what happens:
prefixes = 'JKLMNOPQ'
suffix = 'ack'
for letter in prefixes:
... if letter == ('O') or ('Q'):
... print letter + 'u' + suffix
... else:
... print letter + suffix
...
Juack
Kuack
Luack
Muack
Nuack
Ouack
Puack
Quack
What you can do instead is this:
for letter in prefixes:
if letter in ['O', 'Q']:
print letter + 'u' + suffix
else:
print letter + suffix
Oh, ok. Sorry, my bad :)
So there is a special use for ==. I must look into this.

Well you did come up with a way that would work sort of and you seem to be
ont eh right track. I would make 1 small change if using your approach.
prefixes = 'JKLMNOPQ'
suffix = 'ack'
for letter in prefixes:
if letter == 'O' or letter == 'Q': print letter + 'u' + suffix
else: print letter + suffix
However there are other methods to solve this problem but following the
logic you are using this works.

I also learned an easier way to do that:

if letter == ('O') or ('Q'):

Hi, It seems that whenever I click the QUIT button the TK windows freezes, then I have to CTRL-ALT-DEL to be able to shut it down.

Well this OOP stuff is realy hard for me as I have never even
programmed it took me a while just to understand defs.
That's OK, OOP is quite a strange concept for many folks. Its
actually easier to learn as a beginner than for folks who
have been programming without OOP for a long time!
determined to learn how to do it. My biggest problem is with
__init__
I still don't understand how to use it.
init is simply where you initialise the data attributes of your class.
It could be defined as a normal method and you call it explicitly:
class Message:
def init(self, txt = 'Hello world'):
self.text = txt
def sayIt(self):
print self.text
And every time you create a message object you explicitly call it:
m = Message()
m.init('Hiya fred!')
m.sayIt()
I was having problems with the __init__ too.
class Message:
def init(self, txt = 'Hello world'):
self.text = txt
def sayIt(self):
print self.text
And every time you create a message object you explicitly call it:
m = Message()
m.init()
m.sayIt()
m.init(Hello World is so overdone. It hard to break tradition though :-)
m.sayIt()
Why did you put 'Hiya fred!' in place of having m.init print Hello World?
Now what are dictionaries and the __name__ really used for? A byte of
python never got that through my thick skull.
