Exercise 4 (graded) Write a function "passValidate" that takes a string "s" and checks the validity of string as a password Validation Rules: At least 1 lowercase letter between [a-z] and 1 upper case letter between [A-Z]. At least 1 number between [0-9 At least 1 character from [$#@]. Minimum length 6 characters. Maximum length 16 characters. CS103-Lab 13 Page 3 of 3 Sample Input: s"Uab@2762" Sample Output: True

Answer 1

def passValidate(s: str):
    lower_count, upper_count, digit_count, char_count = 0, 0, 0, 0
    for ch in s:
        if ch.islower():
            lower_count += 1
        if ch.isupper():
            upper_count += 1
        if ch.isdigit():
            digit_count += 1
        if ch in "$#@":
            char_count += 1
    return 6 <= len(s) <= 16 and lower_count >= 1 and upper_count >= 1 and digit_count >= 1 and char_count >= 1


# below is a testing code, remove below lines before submitting the code..
print(passValidate("Uab@2762"))
print(passValidate("Uab2762"))  # prints false. no symbol
print(passValidate("uab@2762"))  # prints false. no uppercase
