refactoring a group of import statements

[GrayShark]

Thanks for the help Thomas Jollans. Just what I needed. I was wondering
what the:
	__import__(name, globals={}, locals={}, fromlist=[], level=-1)

globals was (that was from the docstring on __import__. Odd, the doc on 
www.python.org has globals as a list, not a dictionary). In any case, I 
had a feeling it was the answer; I just didn't know how to do it. 

--Example test--
Python 2.6.4 (r264:75706, Jun  4 2010, 18:20:31) 
[GCC 4.4.4 20100503 (Red Hat 4.4.4-2)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> dir()
['__builtins__', '__doc__', '__name__', '__package__']
>>> x = 'string'
>>> dir()
['__builtins__', '__doc__', '__name__', '__package__', 'x']
>>> globals()[x] = __import__( x )
>>> dir()
['__builtins__', '__doc__', '__name__', '__package__', 'string', 'x']
>>> 
--ends--

That was what I was looking for. All the rest, the arguments were 
unhelpful. 

Question: If you can't answer the question, why are you talking? 

I'm American Indian. That's what I was taught. We don't talk that much. 
But you get an answer when we do talk. Makes life simpler.

Thanks you again Thomas Jollans.
