Simple Password Checker

[Dexty]

I've been trying to write a script that simply checks the strength of a password but the results aren't satisfactory. I know there are other ways to do it but I want to accomplish the task with the 'for' loop method:

import string

def checkPasswordStrength(password=' '):
    
    lowy = string.ascii_lowercase
    uppy = string.ascii_uppercase
    digity = string.digits
    puncy = string.punctuation
    try:    
        if len(password) <= 6:
            print("Password must be at least 7 characters")
    finally:
        for i in password:
            if i not in lowy:
                print("At least a lowercase must be included")
            elif i not in uppy:
                print("At least an uppercase letter must be included")
            elif i not in digity:
                print("At least a number must be included")
            elif i not in puncy:
                print("At least a special character must be included")
            else:
                print('Now That is a Strong Password!')


checkPasswordStrength('Billycash')

I get this response:

Output:
At least a lowercase must be included
At least an uppercase letter must be included
At least an uppercase letter must be included
At least an uppercase letter must be included
At least an uppercase letter must be included
At least an uppercase letter must be included
At least an uppercase letter must be included
At least an uppercase letter must be included
At least an uppercase letter must be included
