How to Call a Python Function on Button Click Event in Flask

To call a Python function on a button click event in Flask, you can use HTML forms and route handling. Create an HTML form with a button, setting the `action` attribute of the form to a specific Flask route. In the Flask route, define a function that executes the desired Python code. When the button is clicked, the form submits a request (typically POST) to the specified route. The Flask route function then handles this request, executes the Python function, and can return a response to update the webpage, such as rendering a new template or updating the existing page with the results. You'll need to use the `request` object in Flask to access form data if needed.
