  As was said, you usually don't need such a thing. If you desperatly 
looking for it, something like this might work:

func = None

def caller():
     assert func, 'func is None'
     return func()

def foo():
     return 'foo'

def bar():
     return 'bar'

func = foo

print func()

Of course, in this case you'd better pass an actual function as a 
parameter. But, again, almost for sureit's a flaw in your design.
