If you decide to look at the source, look for the strip
function/method in the following files:
The first contains the implementation of the method on string
objects. The second is the implementation of the function that you
get by doing "import string".
As an advanced exercise, install Pyrex/Cython, then implement the
strip function using that.
For more on Cython/Pyrex, see: http://wiki.cython.org/.
Cython/Pyrex is a Python-like language for writing Python C
extensions in a Python-like language. Pyrex/Cython gets you much
closer to C code than Python.
