Re: [pygame] Python Question

[Jasper <jasper@xxxxxxxx>]

The short answer is that the variable you passed in is a copy of a 
reference.  You can't change the caller's copy directly, although if 
it's a data structure like a list or dictionary, you can modify it's 
contents.  If you're dealing with something like a string or integer, 
you'll need to return any changes the caller needs to know about, so 
that the caller can change it's copy.

foo = 3
def bar( a ):
   return a + 1
foo = bar( foo )  # foo now equals 4

The long answer is that you're right, this isn't the right place to ask. 
For simple things like this, you're best off getting a python 
programming book.  I like "Python, Essential Reference"

Cheers,
