No, but it is easily rewritten.  Let's see... (untested)


import whrandom

def shuffle(items):
    """Shuffle ITEMS in place.  ITEMS should normally be a list."""
    for top in range(len(items)-1, 0, -1):
        index = whrandom.randint(0, top)
        items[index], items[top] = items[top], items[index]
