Removing modules from the global namespace

[Chris Jaeger]

Hi Bjorn,

	Forgive me if this should be obvious; this is
my first real exposure to python. 

	I have a python program that I want to import
a number of modules into, but I don't know what the
set of modules are going to be until run-time. Each
loadable module exports an identical API. My layout
currently is:

main.py
modules
 \_ __init__.py
 \_ module1.py
 \_ module2.py	
 \_ ...
 \_ moduleN.py

	main.py imports modules, uses dir(modules)
to get the list of names of imported modules, and then
cycles though each module calling some function.
Is there a better idiom to handle this than the one
I am using? I would rather not modify modules/__init__.py
every time a new module is placed in the modules directory.

Thanks,
Chris
