Password checking

[Mekire]

re?

I can't do it. Regular expressions are my weakness.

Neah, let's get sadistic:

def check(password):
    test = (str.isdigit, str.isupper, str.islower)
    good_enough = all(any(f(p) for p in password) for f in test)
    return len(password) >= 8 and good_enough

Note: if you try to turn the above into a professor and you don't know basic python they will get very suspicious.
