Installing Python at Work
I'm currently learning Python for my own use. I'm considering installing it on a work laptop, knowing that it is non-licensed, distributable software. However, does it access communication ports? I know the company checks their ports regularly for activity. I won't be doing anything very serious; I'm just trying out Python, learning the basics from 'Learning Python' by O'Reilly. -- http://mail.python.org/mailman/listinfo/python-list
Re: Installing Python at Work
Many thanks. I know it sounds like a silly question, but it's the company's laptop etc. Does Python allow conflicting statements? :) -- http://mail.python.org/mailman/listinfo/python-list
cron job times out
Hello, I have a few lines of code retrieving a web page and saving some variables from it to a log.

making 'utf-8' default codec
Hi there,
Is there a way of making 'utf-8' default codec for the whole program, so
I don't have to do .encode('utf-8') every time I print out a string?

Yes, thanks for your quick responses, all three. You're right, I don't
want to debug python :-) But I figured out that I don't need captured
exceptions, the thing is that I just didn't belive the problem was that
obvious. In fact, problem was in the except block, not in it's try
block. The except block had this inocent statement:
print self.sect[1].encode('utf-8')
Which results in:
Traceback (most recent call last):
File "AIDbot2.py", line 238, in ?
bot.checkNominations()
File "AIDbot2.py", line 201, in checkNominations
if sect.parseSect() == 1:

print self.sect[1].encode('utf-8')
UnicodeDecodeError: 'ascii' codec can't decode byte 0xfc in position 15:
ordinal
not in range(128)
Now, who can it complain about 'ascii' when I said loud and clear I want
it to encode the string to 'utf-8'??? Damn unicode.

I use wx on both windows and gnome respectively, and on both platforms wx widgets look and feel native. The layout system is really simple to use, but powerfull, and if you've done some web design in the past you are going to wrap your head over it just after a few examples. I think the most powerfull feature of the wxwidget toolkit it's a very consistent API. Each widget is created in a very similar manner, so is very easy to pick and implement new features of the widget. Which can speed up the learning process quite a bit.

It has a DNS server and default gateway configured, and that DNS server and default gateway don't see the rest of the Internet, just the local network. But, I know an IP address of another DNS/gateway pair which is used to access the Internet, and I can ping them (and send nslookup queries) from my machine.

including constants
Hi there, I have a simple problem and I know how to solve it :-D, but I suspect that there is a standard solution which is more elegant. So, here is my problem: I have django app versioned with svn and I test my trunk on two different machines (one with mysql, another with sqlite3). How do I remove database-definition constants from my settings.py and put them in a separate file which wouldn't be maintained by svn? (did I really hear somebody call that kind of file "unversioned file" or did I make that up?) I suppose I could make a trivial module with database info, import it and then assign my constants with data from that module, but that looks so unelegant to me.

If I remove those lines, those 3 methods return None or []. Seems like __init__ won't run __parse, but other methods run it without problem. So, what obvious thing am I missing? :-) -- "Now the storm has passed over me I'm left to drift on a dead calm sea And watch her forever through the cracks in the beams Nailed across the doorways of the bedrooms of my dreams" -- http://mail.python.org/mailman/listinfo/python-list
what difference does redirection make?
When I execute n...@rilmir:~/code/simplepyged/docs/examples$ python latex.py I get expected output (bunch of latex markup). But, when I add a redirection, I get: n...@rilmir:~/code/simplepyged/docs/examples$ python latex.py > foo.tex File "latex.py", line 87, in print mytemplate.render_unicode(stack=stack, index=latex_index(stack), pages=pages) UnicodeEncodeError: 'ascii' codec can't encode character u'\xe9' in position 625: ordinal not in range(128) Now, how does python even know I added a redirection?! And then... why would it care? Code of latex.py can be seen here: http://github.com/dijxtra/simplepyged/blob/5ad8e0f14e93bde74520b502e5af71d78ed55bf0/docs/examples/latex.py -- "Now the storm has passed over me I'm left to drift on a dead calm sea And watch her forever through the cracks in the beams Nailed across the doorways of the bedrooms of my dreams" -- http://mail.python.org/mailman/listinfo/python-list

Thank you, thank you, thank you! I got it now...

downcasting problem
Hi everybody, I need to downcast an object, and I've read repeatedly that if you need to downcast, you did something wrong in the design phase. So, instead of asking how do you downcast in python, let me explain my situation. I have a 2-pass parser. 1st pass ends up with a bunch of superclass object, and 2nd pass is supposed to downcast those to one of subclasses so I can work with them. Details: I have a file full of lines which I parse into Line objects. I also have two subclasses of Line, namely Individual and Family. Constructor of both subclasses needs all Line objects in the file to be constructed, so I cannot construct subclass objects in the first pass. The Python way of doing this (as I understand it) would be to wrap a subclass around Line and have the Line object as an attribute of a subclass. Now, this obviously breaks polymorphism and I now have to reimplement all of Line's classes in subclasses. Although reimplementation is simple (def method(self): return self.line.method()), that way of doing things is just not elegant. So, is there any more elegant solution to my problem? Thanks in advance. -- "Now the storm has passed over me I'm left to drift on a dead calm sea And watch her forever through the cracks in the beams Nailed across the doorways of the bedrooms of my dreams" -- http://mail.python.org/mailman/listinfo/python-list
