You don't need to do all that list manipulation.  This is probably quicker:

def random_number():  # Unused "id" parameter omitted
    characters = (string.ascii_lowercase +
                  string.ascii_uppercase +
                  string.digits)
    return ''.join(random.choice(characters) for i in range(6))

Cheers,
Ian
