How to quickly check if given password is strong enough

Recently i needed to quickly check that password is strong enough in accordance with customer requirements :

  • Passwords will contain at least (1) upper case letter
  • Passwords will contain at least (1) lower case letter
  • Passwords will contain at least (1) number or special character
  • Passwords will contain at least (10) characters in length
  • Password maximum length is 64

Here's what i got with python :

import re

# Passwords will contain at least (1) upper case letter

# Passwords will contain at least (1) lower case letter

# Passwords will contain at least (1) number or special character

# Passwords will contain at least (8) characters in length

# Password maximum length is not limited

def test_password(password):
  return re.match(r'?=^.{10,64}$)((?=.*\d)|(?=.*\W+))
                  (?![.\n])(?=.*[A-Z])(?=.*[a-z]).*
