Validation of a Password - Python

Question

I am currently working on a code that will validate the password on the following basis:

Is at least 8 characters long

Contains at least 1 number

Contains at least 1 capital letter

Here is the code:

def validate():

    while True:

        password = input("Enter a password: ")

        if len(password) < 8:

            print("Make sure your password is at lest 8 letters")

        elif not password.isdigit():

            print("Make sure your password has a number in it")

        elif not password.isupper(): 

            print("Make sure your password has a capital letter in it")

        else:

            print("Your password seems fine")

            break

validate()

I'm uncertain what is wrong in my code, when I enter a password that has a number - it displays that I need a password with a number in it. Any solutions?

Answer 1

There was some issue in your code, it is better to use the 're' module or package when used with regular expressions.

With it your code would look like this:

import re

def validate():

    while True:

        password = raw_input("Enter a password: ")

        if len(password) < 8:

            print("Make sure your password is at lest 8 letters")

        elif re.search('[0-9]',password) is None:

            print("Make sure your password has a number in it")

        elif re.search('[A-Z]',password) is None: 

            print("Make sure your password has a capital letter in it")

        else:

            print("Your password seems fine")

            break

validate()
