I'd suggest sticking to the basics and learning more advanced features
as you need them to solve real problems.

Python is case sensitive (i.e. you must use case consistently).
 
>     exec "C = simple(a)"
>     print C

Why would you write this? You should very very rarely need to use exec
and eval.
