Hello guys,
I'm trying to learn python by making some small programs that could be
useful for some bigger propouses. In fact, i've made a small "check
latest-modified" for webpages and it's working great.
The next step I would like to do is to check if I have new e-mails (I
don't wanna read it fr

So, it's more important to protect against typos than subtle bugs?

I am familiar with srvany. Seems like it is a whole bunch easier than
the PyWin32 stuff.
I'll write a wrapper script that can be used like this:

There's always the new 'with' statement in Python 2.5. So instead of

...you do:
with open('foo','r') as f:
for line in f:
print line
It's at least a little bit cleaner, and it will clos

Oh, I have no idea (didn't download). I just sort of assumed if you had
included calldll you probably hadn't included ctypes.

Don't do object persistence. What is an object? It's a combination of code
and data. Code structure is internal to your program--it has no bus
Hi All,
Not being able to figure out how are partial classes coded in Python.
Example: Suppose I have a code generator which generates part of a
business class, where as the custome part is to be written by me. In
ruby (or C#), I divide the code into two source files. Like this:
GeneratedPerson.

Hi Sanjay,
To the best of my knowledge, Python currently has no support for
partial classes.
However, BOO (http://boo.codehaus.org/) - which is a Python-like
language for the .NET CLI)- _does_ support partial c
