Well,
I was somewhat confused with all of the answers so I decided to go with
my/following method. Kent's method has 4 fewer lines of code than mine and
cleaner. Please correct me if I am fundamentally wrong.

You are correct. It is missing the ":" and it will print "3"

Note that split() splits on any whitespace, not just line endings. In
your case it doesn't much matter I guess.

1. Put the data in a Python module and import it
2. Put the data in a .ini file and read it with the ConfigParser
module http://docs.python.org/lib/module-Config
Augghh! I can't stand it!!! If position is a boolean, then *why* must we
test if it is equal to True?!!! It's a boolean! Just test it! For that
matter, let's rename "position" to something a little more direct,
"print_line" perhaps?
Did you know that files are now iterators? If going through

Don't forget about the newline...(that makes four!)

Why do you need to use regular expressions? This problem

I'm playing around with pyGTK, and I have a question to see if I'm
understanding things correctly.
Is a method just a function inside a class?
i.e.
def myFunction():
print "This is a function"
class myClass:
def myMethod():
print "This is a method"
and to call:
myFunction()

Pretty much. It also has a required 'self' parameter which gets the

If you give some examples of what you want to parse we can give more
specific advice.

The problem is that i need to to that directly from

PyYaml is an option too. [1]

It´s very readable and is converted to a Python native structure/object.
