--description--

Now it's time to test your function. Uncomment the last two lines in your code and modify the function call passing 5 arguments. Use 8 for the length and 1 for the other four constraints.

--hints--

You should call generate_password with the provided arguments.

js
({ test: () => assert.match(code, /^new_password\s*=\s*generate_password\s*\(\s*8\s*,\s*1\s*,\s*1\s*,\s*1\s*,\s*1\s*\)/m) })

You should print your new_password variable.

js
({ test: () => assert.match(code, /^print\s*\(\s*new_password\s*\)/m) })

--seed--

--seed-contents--

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

    return password
