Strings are immutable in python; it means you cannot change them
in-place.  You can still change the value of variables and do things like:
a = "hello"
a = "a" + a[2:]  # producing allo

Strings are immutable, but there's (mutable) containers that might do a 
better job for what you want to do.  Module array could be a possible 
solution (and I'm sure there's others).
