Learn Regular Expressions by Building a Password Generator - Step 40

Tell us what’s happening:

The feedback is that I “should add a third tuple to the constraints list using uppercase as the first item”- which I did. But I don’t understand the second part: I have to add “a character class that matches a single uppercase letter as the second item.”

Thoughts?

Your code so far

import re
import secrets
import string


def generate_password(length, nums, special_chars, uppercase, lowercase):
    # Define the possible characters for the password
    letters = string.ascii_letters
    digits = string.digits
    symbols = string.punctuation

    # Combine all characters
    all_characters = letters + digits + symbols

    while True:
        password = ''
        # Generate password
        for _ in range(length):
            password += secrets.choice(all_characters)

/* User Editable Region */

        constraints = [
            (nums, '[0-9]'),
            (lowercase, '[a-z]')
            (uppercase, '[]')
        ]        

/* User Editable Region */

    return password
    
# new_password = generate_password(8)
# print(new_password)

pattern = '[^a-z]t'
quote = 'Not all those who wander are lost.'
# print(re.findall(pattern, quote))

Hello Imoh,

So in the second tuple you added lowercase and the regex pattern for a single lower case letter.

Now for this question you already added the upercase, and need to add a single upper case letter.

Can you look at the second tuple, and figure out how to make a regex pattern for the uppercase letters instead of lowercase?
