The problem here is that you are typing it all at the >>> prompt.
If you look closely you will notice that the code examples are in
different modules - ie different files.

The >>> prompt basically acts like all the code you type is in the
same module, namespaces are really only effectoive when you are
using multiple files/modules.

However I'll refrain from saying much more since I do think the
namespaces topic could be significantly improved if only I could
find better words and examples.

So please everyone, feel free to try to explain this idea to Payal
so that I can steal your ideas for the tutorial!!  :-)
