you can do this:

import f1
import f2

f =f1. f
f()
f=f2.f
f()

or mess with the imp module.
or, do the tricky thing:

---------------- f2.py
def f():
    print "f2"
---------------- f2.py

---------------- f.py
def f():
    print "f1"

fun = f
fun()

file = open("f2.py")
text = file.read()
exec(text)

fun = f2
fun()

---------------- f.py

but i think you sohuld stick with import.
