You can look up the function in the globals() dict, or you can import
__main__, which is the top-level module, and use getattr() on it. Or you
could wrap your functions in a class...
def OnMenuFindMe():
print 'You found me'
f = globals()['OnMenuFindMe']
f()
import __main__
g = getattr(__main__, 'OnMenuFindMe')
g()

this is a nice way
func = getattr(obj, "method", None)
if callable(func):
func(args)
