Numbers in Python are already immutable.  What you're really looking for
is a programming style where you don't bind any variable more than once.

This gives rise to a programming style that Python can support to a
certain extent, but for which some other languages are designed from the
beginning.

You might look at http://learnyouahaskell.com (online book) if you want
to try the above approach.
