This is almost certainly a homework problem.  We are very restricted in 
what we can do to help.  See:

These are basic list manipulation concepts.  See any Python tutorial that 
talk about lists.  For example:

Other than refering you to tutorials, I don't think I can do much else 
here.  Good luck.
