判断你设置的密码的强度

def judgePasswordStrength(password):
strengthLength = max(0, len(password) - 5)
from string import ascii_lowercase, ascii_uppercase, digits, punctuation
flags = [bool(set(password) & set(s)) \
for s in [ascii_lowercase, ascii_uppercase, digits, punctuation]]
return min(flags.count(True), strengthLength)
