Our three weapons are:

(1) fully qualified names: 

    import random
    random.shuffle

(2) unqualified local imports: 

    from random import shuffle

(3) local name binding: 

    import random
    shuffle = random.shuffle

(4) messing about under the hood:

    shuffle = __import__('random', fromlist=['shuffle']).shuffle

(5) and a fanatical devotion to the Pope.


A serious question -- what is the point of the fromlist argument to
__import__? It doesn't appear to actually do anything.
