Tell us what’s happening:

I’ve read some solutions on the forum and some say something like this

pattern = '.+[^a-z]'

And the console displays the entire string, but it still doesn’t work

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

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

# User Editable Region

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

# User Editable Region

Yeah, it works, but the [^a-z] is obsolete in the pattern. Test expects the whole pattern to consist just of the dot followed by the + quantifier.
