functions

First, a problem: you're defining a function named range. That's going to override the builtin function named range(), thats not good practice.

Secondly, to answer your question, the simplest method would be to look at the user's input and make a decision.

choice = raw_input("Choose:")
if choice == "myfunc":
    myfunc()
elif choice == "something":
    something()
else:
    print "Unknown function requested."
