It all depends on your needs. If you have to deal with user
input to get the name of the module, better use __import__
than exec. __import__ works just like the normal import call:
import sys
is equal to:
sys = __import__('sys')
If you need, let's say, to search for a module that lies
outside sys.module paths, then use imp's functions.
