Why This Works

Rendering the HTML: The subsequent call to render the HTML is now clearer and ensures that there are no mishaps with NoneType elements.

Clearer Flow: The logical segmentation makes the code easier to understand and debug.

Additional Tips

Error Handling: Implement error handling to check if current_url is successfully fetched before attempting to access .html. You can do this by checking the response status:
