If you are really trying to learn Python, you really owe it to
yourself to study Grant's replies.  You are using constructs
from some previous language that you learned and trying to
apply them to Python.  IMHO Python programmers would never use
s=c+s on strings as it is quite inefficient.  The methods
and functions he uses reversed(), .join(), list() are very
powerful Python constructs that you will need to learn how
to use.  The slicing word[-1::-1] is also something that
will come in handy later if you learn how to use it.  This
is a simple example that you can learn a lot from if you
will study Grant's responses.

Just my two cents.
