Sure, I'd be happy to provide you with a tutorial on how to call a Python function from JavaScript in a Flask application. In this example, I'll assume you have a basic understanding of Flask, Python, and JavaScript.
Firstly, make sure you have Flask installed. If not, you can install it using:
Now, create a new Flask application. Create a file named app.py:
In the code above, we have a simple Flask application with a route /api/call_python_function that will be responsible for handling the request to call our Python function.
Create a folder named templates in your project directory and inside it, create a file named index.html:
This HTML file contains a button that, when clicked, will trigger a JavaScript function (callPythonFunction) that makes an AJAX request to the Flask route we defined earlier.
Save your changes, and run your Flask application:
Visit http://127.0.0.1:5000/ in your web browser to see the page.
Click the "Call Python Function" button on the webpage. You should see an alert with the response from the Python function.
That's it! You've successfully set up a Flask application that allows calling a Python function from JavaScript. You can extend this example by adding more complex Python logic or enhancing the JavaScript functionality as needed.
