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, r'\d'),
            (lowercase, r'[a-z]'),
            (uppercase, r'[A-Z]'),            
            (special_chars, fr'[{symbols}]')            
        ]

Hello and welcome to the forum!

Please describe your problem when posting a question. The solution isn’t always as obvious as here:

You don’t have to repeat the length method, just compare constraint to the existing one.

wow. lets ignore that i couldnt solve that lol. :upside_down_face:

When you are learning Python as a second language, you might find yourself writing more code than necessary all the time, I speak from experience.

You first have to get used to Python abstracting a lot of the code away from you.

Hello! I have faced the same issues
here is my code: for constraint, pattern in constraints:
len(re.findall(pattern, password))
constraint <= len(re.findall(pattern, password))
i have tried so many other ways but none of them worked
for instance:
for constraint, pattern in constraints:
len(re.findall(pattern, password))
if constraint <= len(re.findall(pattern, password)):
pass
2) for constraint, pattern in constraints:
len(re.findall(pattern, password))
constraint <= len(re.findall())
none of these worked. Could you help me please ?

Hello

put constraint in front of the length method and compare both, all in the same line.

No extra code and no changes of the the original code.

I solved it thank you!

I’m trying to understand the lesson topic:

Step 57

compare constraint and the length of the list returned by findall() . Use the <= operator for that.

Check constraints

    for constraint, pattern in constraints:
        constraint <= len(re.findall(pattern, password))
