Tell us what’s happening:

PLease tell me where’s the error ?
if all([
constraint <= len(re.findall(pattern,password))
for constraint,pattern in constraints
]):
break

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

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

# User Editable Region

    return password
new_password = generate_password(12, 2, 2, 2, 2)
print(new_password)
# new_password = generate_password(8)
# print(new_password)
