Try this:
>>> from sys import exit
>>> globals()
{'__builtins__': <module '__builtin__' (built-in)>, '__name__':
'__main__', 'exit': <built-in function exit>, '__doc__': None}
>>> afunc = globals()["exit"]
Do you really need to use the "from X import Y" style? Consider the
following alternative:
>>> import sys
>>> afunc = getattr(sys, "exit")
