random.randrange

[perfringo]

Maybe I am missing something but from documentation: random.randrange

random.randrange(stop)
/../
Return a randomly selected element from range(start, stop, step).

Why random.randrange(0, random_characters + 1) and not justrandom.randrange(len(alphabet)). Latter will give random number which is in range of valid indexes:

>>> a = [1, 2, 3]
>>> len(a)
2
>>> max(random.randrange(0, len(a) + 1) for x in range(100))
3
>>> max(random.randrange(len(a)) for x in range(100))
2
>>> a[3]
Index Error
