this is untested code, but it might give you some ideas:

import os
import usefulmodule

def ask():
    usereditor = raw_input("What's your choice of editor?")
    return usereditor

try:
    usereditor = os.environ['EDITOR']
except KeyError:
    usereditor = askforeditor()

usefulmodule.dostuff(usereditor)
