how to do this code with one if statement with condition list comprehension

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}]')            
        ]

        # Check constraints

/* User Editable Region */

        # list comprehension
        count = 0        
        for constraint , pattern in constraints:
            
                if constraint <= len(re.findall(pattern,password)):
                       count += 1
        if count == 4:
            break
        


/* User Editable Region */

            break

    return password

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

Have you tried something?

A list comprehension is like backwards syntax of a for loop. You need to transform this for loop into a list comprehension

for element in list:
    print(element)

Transforms into:

[print(element) for element in list]

I hope this helps!
