module confusion

[rjcarr]

Sorry if this is a completely newbie question ...

I was trying to get information about the logging.handlers module, so
I imported logging, and tried dir(logging.handlers), but got:

AttributeError: 'module' object has no attribute 'handlers'

The only experience I have in modules is os and os.path ... if I do
the same thing, simply import os and then type dir(os.path), it
displays the contents as expected.

So my question is ... why are they different?  I mean, in terms of
designing these modules, how would you go about getting a sub-module
in your name space?  And on the other side, how would you go about
getting it out?

Thanks!
