After the import and assignment you already have, assuming you want all possible lengths with the same probability:

import random

length = random.randrange(5, 16)

randstr = ''.join(random.choice(letters) for _ in range(length))

@Hulk, as the docs at docs.python.org/library/random.html#random.randrange say, randrange was new in version 1.5.2. No idea why you think you can't use it 8 versions later than than time?!
