I could make it shorter in Python as well. But for a newbie that haven't seen
the docs for strings in Python I thought the terse version would be more
interesting.
At least he'll see that there are methods to do what he wants already builtin
with the language.

If I were writing in Perl I'd not use substr like this and would write code
similar to the one the OP posted (i.e., /^track=(.*)/).

I like them as well. I just don't see the need to use them everywhere. :-)
