I have a question about the split function? surpose a = |,and when I use
a.split(|) , I got the list
[',] ,but I want to get the empty list,what should I do ?
Something like...
[x for x in |.split(|) if x]

p.s. Is Python seeing a lot of use at Ubisoft or is this just for personal

perhaps both)?
We do use Python a fair bit, mostly for build systems and data mining, but also
because it's the built-in script language for Motionbuilder.

This issue bit me once too often a few months ago, and now I have a class
called
O from which I often subclass instead of from object.
Its main purpose is a friendly __str__ method, though it also has a friendly
__init__.
Code:
class O(object):
''' A bare object subclass to
I have no idea why using __repr__ versus __str__ would make any difference in
the
order of the attributes. They're going to come out in the order you specify,
regardless of what you name your method. If you don't like the arbitrary
order you
get from the dictionary, then either sort it,
It's also helpful to not have to display every attribute, of which there
may be
dozens.
Do I detect a code smell here?
Possibly. I'll often try to subdivide into several simpler types, but sometimes
that makes the code more complex than it needs to be.

I think so, Murphy's law dictates that the attribute you're interested in
will not be
displayed anyway.
That's what __repr__'s for.
