Validation of a Password - Python

Question

So I have to create code that validate whether a password:

• Is at least 8 characters long
• Contains at least 1 number
• Contains at least 1

Answer 1

''' Minimum length is 5;
 - Maximum length is 10;
 - Should contain at least one number;
 - Should contain at least one special character (such as &, +, @, $, #, %, etc.);
 - Should not contain spaces.
'''

import string

def checkPassword(inputStr):
    if not len(inputStr):
        print("Empty string was entered!")
        exit(0)

    else:
        print("Input:","\"",inputStr,"\"")

    if len(inputStr) < 5 or len(inputStr) > 10:
        return False

    countLetters = 0
    countDigits = 0
    countSpec = 0
    countWS = 0

    for i in inputStr:
        if i in string.ascii_uppercase or i in string.ascii_lowercase:
             countLetters += 1
        if i in string.digits:
            countDigits += 1
        if i in string.punctuation:
            countSpec += 1
        if i in string.whitespace:
            countWS += 1

    if not countLetters:
        return False
    elif not countDigits:
        return False
    elif not countSpec:
        return False
    elif countWS:
        return False
    else:
        return True


print("Output: ",checkPassword(input()))

With Regex

s = input("INPUT: ")
print("{}\n{}".format(s, 5 <= len(s) <= 10 and any(l in "0123456789" for l in s) and any(l in "!\"#$%&'()*+,-./:;<=>?@[\]^_`{|}~" for l in s) and not " " in s))

Module import

from string import digits, punctuation

def validate_password(p):
    if not 5 <= len(p) <= 10:
        return False

    if not any(c in digits for c in p):
        return False

    if not any(c in punctuation for c in p):
        return False

    if ' ' in p:
        return False

    return True

for p in ('DJjkdklkl', 'John Doe'
, '$kldfjfd9'):
    print(p, ': ', ('invalid', 'valid')[validate_password(p)], sep='')
