I’ve tried this

if len([(constraint, pattern) for constraint, pattern in constraints if constraint <= l

but it doesn’t seem right… But I don’t get it, any other python compiler runs it smoothly.
Here’s the whole code:

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}]')            
    ]

    # Check constraints
    if len([(constraint, pattern) for constraint, pattern in constraints if constraint <= len(re.findall(pattern, password))]) == 4:
        break

    #if len(new_constraint_list) == 4:
    #    break
return password

new_password = generate_password(8)

print(new_password)

Sorry I’m new to the platform. Back then I didn’t realise it would append my question to an already opened topic, I guess I thought the topics list was a sort of “category”. Thank you
