Tkinter runs on your local machine. HTML/JavaScript runs in a web browser. So you can't directly embed Tkinter in HTML because they operate in completely different environments. Here are a few things I can suggest:

• If it's a desktop app, use Tkinter by itself, don't try to mix it with HTML.

• If it's a web app, replace Tkinter with a web framework (Flask, Django) + HTML/CSS/JavaScript.

• If it's both, run Tkinter on the backend and communicate with a web frontend via an API.
