You can do it with a class using the __getattr__ function. There might be a
way to do it without a class but I don't how to do it that way.
class AllMyFunctions(object):
def a(self):
print "Hello. I am a."
def b(self):
print "Hey. I'm b."
x = raw_input("Enter a function to call: ")
if x not in AllMyFunctions().__dict__:
print "That's not a function that I have."
else:
getattr(AllMyFunctions(), x)()
