Question

Write a program that validates passwords based on the following requirements:
• must be at least 8 characters in length
• must include at least 1 alphabet character
• must include at least 1 number

The program should implement the password checker using a function name validate_password,
which takes two strings as input and returns one of the following:
• 0 if the passwords match and fulfill all requirements
• 1 if the passwords are not the same length
• 2 if the a number is not found
• 3 if an alphabet character is not found

In main, test your function validate_password by creating 4 sets of passwords and which match one of the conditions listed above and printing the result.

Answer 1

Code written in python:

def validate_password(password1, password2):
    if len(password1) != len(password2) and len(password1) >= 8: # checks the length of two passwords
        return 1

    elif password1.isalpha(): #checks if the password is not only alphabets that does it contain number or not
        return 2

    elif password1.isnumeric(): #checks if the password is not only numeric that is does it contain alphabet or not
        return 3

    else:    #for correct password
        return 0

if __name__ == '__main__':
    res = validate_password("qwer45678", "qwer45678") #perfect password
    print(res)
    res = validate_password("qwer4567", "qwer45678") # difference in length
    print(res)
    res = validate_password("qwertyuv", "qwertyuv") # only alphabets
    print(res)
    res = validate_password("12345678", "12345678") # only numbers
    print(res)

Output:

len() helps in verifying length of both passwords

isalpha() helps in checking that the number password contains only alphabet i.e it will be true when the password contains only alphabet and false if the password is alphanumeric

isnumeric() helps in checking that the number password contains only numbers i.e it will be true when the password contains only numbers and false if the password is alphanumeric

So in both isalpha() and isnumeric() if value is True then we return 2 and 3 and in the end else we will return 0
