```js
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'),
            (special_chars, fr'[{symbols}]'),
            (uppercase, r'[A-Z]'),
            (lowercase, r'[a-z]')
        ]

        # Check constraints        
        if all(
            constraint <= len(re.findall(pattern, password))
            for constraint, pattern in constraints
        ):
            break
    
    return password
    
new_password = generate_password(length=8, nums=1, special_chars=1, uppercase=1, lowercase=1)
print(new_password)

```

Please format your code in triple backticks, like so:

````auto
```py
Your code here...
```

````

Thanks.

can you give a link to the step?

I’ve edited your post to improve the readability of the code. When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.

You can also use the “preformatted text” tool in the editor (`</>`) to add backticks around text.

 ![Pre-formatted-text](https://global.discourse-cdn.com/freecodecamp/original/3X/1/b/1b18854f1059217f29370444396145cc3a0cd8ae.gif)

See [this post](https://forum.freecodecamp.org/t/forum-code-formatting/25574) to find the backtick on your keyboard.  
**Note:** Backticks (`) are not single quotes (').

Welcome to the forum @rahmad12360

> You should have the `(nums, '[0-9]')` tuple in your `constraints` list.

Also, remove the rest of the tuples. Then instructions did not ask you to add them in this step.

I changed the category to #Python to better reflect the nature of this post.

Happy coding
