I like it before I don't remember using the "any" sentence before. And this is a very simple example.

Interesting, though memory inefficient approach.

You are right. For BIG password. But maybe not. It depends to realisation of "any". Thank for idea.

any() take an iterator, no need for making lists

??? Are you suggest to use () instead [], so that replace list comprehension to generator comprehension ?

<pre class='brush: python'> any([ch.isupper() for ch in data]) and </pre> Using the any builtin is nice, but why stop there and code the rest using list comprehensions? for methodname in ('isupper', 'isdigit', 'islower'): if not any(map(methodcaller(methodname), data)): return False note thhat in python 3 it will be less memory intensive because map will return an iterator (use imap from itertools in python 2 for the same effect)

<pre class='brush: python'> any([ch.isupper() for ch in data]) and </pre> use Regex is better store rules in list and check it within loop

<pre class='brush: python'> any([ch.isupper() for ch in data]) and </pre> I prefer list comprehension. For memory problem, i can just to replace list comprehension to generator comprehension. If honestly, i don't like map and filter.
