Can I ask an unrelated question?  What does that mean -- "you'll have 
the same namespace as the file's module too".

I understand the difference between local/global/builtin namespaces (I 
think): the local namespace is for names specific to the current context 
(a function or class or module, for instance), the global namespace is 
for names available to all contexts, and the builtin namespace is for 
names that are predefined by Python and often start with two underscores.

I'm guessing that the quote above means that the names available to the 
script are now available to the user in the shell, when the shell is 
invoked in this fashion, such that if the script imported from module 
"Stock", all of the names in "Stock" are available and don't need to be 
imported.  But if someone could confirm this it would help me grasp the 
concept of namespaces better.

Thanks,
Erik
