Not sure if this is what you're after, but:

 >>> def importobj(name):
	mod = __import__(name)
	obj = getattr(mod, name)
	globals()[name] = obj
	
# import the StringIO object from the StringIO module
 >>> importobj('StringIO')

# is it in the global namespace? yes:
 >>> dir()
['StringIO', '__builtins__', '__doc__', '__name__', 'importobj']

Putting something into globals() is a bit of a kludge, though.  You're probably 
better off using from x import x.

Cheers,
