--description--

It works, but there are still a couple of things you can improve. First of all, calling a function with 5 arguments can create confusion on which value will be assigned to which parameter.

You can call a function using keyword arguments, that is writing the parameter name explicitly followed by the assignment operator and the value. For example:

py
def add(x, y):
    return x + y

add(x=1, y=7) # 8

Modify your function call to use keyword arguments.

--hints--

Your new_password variable should have the value of generate_password(length=8, nums=1, special_chars=1, uppercase=1, lowercase=1).

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

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 = [

            (uppercase, r'[A-Z]'),
            (lowercase, r'[a-z]')
        ]

        # Check constraints        
        if all(
            constraint <= len(re.findall(pattern, password))
