Have you seen this byt the creator of python -- GvR?

This is an important question: To start off you need to digest whats
the diff between value oriented and object oriented. Since this is
more to do with paradigm than with a specific language you may read
for example:
http://www.haskell.org/haskellwiki/The_Monad.Reader/Issue3/Functional_Programming_vs_Object_Oriented_Programming

In the python data structure world:
value | object
tuple | list
XX    | dictionary
frozen-set | set
