Re: [Tutor] howto call DOM with python

[János Juhász]

hi

there are same samples about it in the activepython 2.4 installation 
folder
c:\Python24\Lib\site-packages\win32comext\axscript\Demos\client\ie\
on my xp, but it isn't working. I have just repaired my activepython and 
reinstalled it but no success.

As I remenber, it was working under activepython 2.3 anyway.


Yours sincerely,

As others have pointed out, browsers only know JavaScript. But take a 
look at pyjamas: http://pyjamas.pyworks.org/ which translates Python 
into browser-specific JavaScript. It is designed around a Python port of 
Google Web Toolkit, but you don't need to use that aspect of it. Of 
course the ability to create web pages using the ported GWT widgets is 
pretty impressive. No more HTML!

Take a look at the pyjamas helloworld example.

Re: [Tutor] "IOError: decoder jpeg not available"

Hello again,

Problem finally solved : had to reinstall and rebuild PIL (from tar) - this
time pointing the setup.py to the right location of jpeg-6b library, and
ONLY THEN running setup.py build_ext -i of Imaging1.1.6

hope someone can make use of this,

Re: [Tutor] Two sys.exit questions

[David Perlman]

If you want to play around with this stuff, you can first import sys,  
and then insert this line in the except clause:
print repr(sys.exc_info())
(or some other way of getting the details out of the returned tuple.)

That will tell you exactly what brought you to the except clause.

I don't think this is possible, at least without creating a
custom-compiled version of Firefox.

There's a little bit of discussion from last year on the python
mailing list here:
http://mail.python.org/pipermail/python-list/2006-November/415805.html

There's some more information available out there if you search for
PyXPCOM or python and nsdom.  If you do end up getting it working, I
would be interested in hearing how it went.

It would if you had a file named 'somefile_you_have.txt' in the same 
working directory as your python interpreter is set to.
If you don't, the f = file( ... ) line will fail to find the file to 
open for input, so it will throw an IOError and print out
"You had an error on file input"
If you do have such a file, the assignment to f will pass successfully, 
sys.exit will throw a SystemExit, and the except block won't catch it 
because it only catches IOErrors.

Within the CGI I think you can look at the environment variable 
REMOTE_HOST or REMOTE_ADDR.

You could also do this by configuring the web server (e.g. apache) that 
is serving the CGI, or some other method of restricting access to the 
computer running the server.

sys.exit raises an exception.  That's how it exits program execution.
If you use it in a try block, the exception it raises will have no 
effect because your except clause isn't catching
a particular kind of error, it's catching all errors (including 
"SystemExit" ones)

an example of a sys.exit working in a try block would be something like 
this:

import sys
try:
   f = file('somefile_you_have.txt','r')
   sys.exit(0)

except IOError:
   print "You had an error on file input"


hope that clears some things up for you.

Re: [Tutor] Two sys.exit questions

[Jason Massey]

When you call sys.exit() you're raising a SystemExit exception.


help(sys.exit)

Help on built-in function exit in module sys:

exit(...)
   exit([status])

   Exit the interpreter by raising SystemExit(status).
   If the status is omitted or None, it defaults to zero (i.e., success).
   If the status is numeric, it will be used as the system exit status.
   If it is another kind of object, it will be printed and the system
   exit status will be one (i.e., failure).

So that explains why you're falling through to except clause.
You can see the same type of behavior if you manually raise an exception
(ValueError for example) within a try clause

In your example concerning the reading and writing to files, as far as a
close() statement goes you would get this error:

try:

... i_file = open('doesnt_exit.tmp','r')
... except IOError:
... i_file.close()
...
Traceback (most recent call last):
 File "", line 4, in ?
NameError: name 'i_file' is not defined




Since i_file never got defined because the open wasn't successful.

BTW don't use file as a variable since it will mask python's built-in file
object

The result is 1 which indicates an error. You don't want
the result you want the outpur, which is a different thing
entirely! :-)

To get the output you need to access the output stream
of the process which is usually stdout. The old way to do
that was with os.popen, but the subprocess module
provides a new way. The m,odule docs describe how
to replace popen using subprocess' Popen class.

My tutorial shows an example of the same thing based
on the odule documentation.

Basically it looks like:

import subprocess
psout = subprocess.Popen(r'c:\abc.exe c:\data\file1',
shell=True, stdout=PIPE).stdout
results = psout.read().split('\n')
Notice I enclosed the command with a raw string.Otherwise your
backslashes get treated as escape characters. This might be why you
are getting error codes back?Another way to avoid that is to use
forward slashes which Python understands on DOS psout =

Nope, just looking for the wrong thing. But you only
know that after you find out :-)

Re: [Tutor] MiniWiki

[Kirk Bailey]

It's a result problem; I do not see the reason it is doing this. AS I do 
not yet understand it, I cannot say where the problem is. Anyone got an 
idea?

I am posting musings and rumbling about my project so anyone who is 
interested may offer suggestions, or simply follow along for their own 
interest and amusement. Who knows, maybe someone will spark an idea off 
of it and gain something.

Re: [Tutor] Telnet and special characters

[David Perlman]

This question isn't well posed.  There is no such thing as an F1  
"character".

Data is sent over telnet connections as 8-bit bytes.  You can send  
any combination of 8-bit bytes you want by coding them in a number of  
different ways, such as chr(xx) like you wrote below, or '\xnn' or  
whatever suits your fancy.  The reason you are having problems is  
that you don't know what bytes you want to send over the connection.   
If you figure that out, then you will be able to send those bytes  
without any further trouble.

If you're having trouble figuring out what bytes you want to send  
over the connection, you need to take a step back and ask what it is  
you're actually trying to do.  What are you sending the data to?  Are  
you trying to emulate something else that would normally be sending  
the data?  Find the documentation for the sending and/or receiving  
ends, and figure out what combinations of characters, escape  
sequences, whatever, are involved in triggering the behavior that you  
want.  Then you will know what bytes you want to send.

If you are emulating something else on the client end, you could fire  
up the regular client and sniff the connection while you hit whatever  
'F1' key you're interested in, and see what actually gets sent over  
the connection when you do that.

Re: [Tutor] Telnet and special characters

[Johan Geldenhuys]

 I have used special characters before in Telnet sessions, but always use
hex characters. i.e.: \x0B for ESC.

Maybe F-keys are some form of internal OS signals and are not send out on
the network connection. In that case, I'm not sure how to send it.

You could have a special sequence of characters that wouldn't normally be
used, like \1\1\2\3\1\2\4, and if the server receives this, you can use
pyHook or something to generate a keypress on the other end.
It seems to me that the function keys would have a value too.
I don't have time to investigate the matter further currently, I'll try to
look into it later.

Is that a question? If so, what do you mean by "it goes banannas, 
misprocessing the link construction"? Is this a Python problem or a link 
problem?

http://en.wikipedia.org/wiki/Guido_van_Rossum

About the origin of Python, Van Rossum wrote in 1996:

Over six years ago, in December 1989, I was looking for a "hobby"
programming project that would keep me occupied during the week around
Christmas. My office ... would be closed, but I had a home computer,
and not much else on my hands. I decided to write an interpreter for
the new scripting language I had been thinking about lately: a
descendant of ABC that would appeal to Unix/C hackers. I chose Python
as a working title for the project, being in a slightly irreverent
mood (and a big fan of Monty Python's Flying Circus).
