I most certainly do not. The point is that you pass a string to 
__import__. :)

so:

modulename = 'sys'
sys = __import__(modulename)

is the same as

import sys

Why do you want to unload a module? Plus, what are you expecting 
"unloading" it to do? If you want to stop code getting at it, simply 
rebind its name:

import sys
sys = None

reload() reloads (wouldja believe it?) a module from disc, if it's 
changed on disc since it was imported. I've never once used it in a 
program, but I use it a lot when testing a new module from the Python 
interpreter. ("import module", test it, damn it doesn't work, 
"reload(module)", test again, go to step 3).
