How @app.route('/') executed the index function? Please explain!

I couldn't understand decorator - @app.route('/'). How it executed the index function? Please explain! Also If i create another function below index function say greet(). The greet does not execute. Why only func below @app.route() is executed?

Basically route tells the server to execute the function under app.route decorator. As far as I know only the function just below the decorator is executed.

This route specify the route in web browser, for example for app.route("/") when you type in web browser 127.0.0.1:8000 you get what the index function returns.

If you want to add to another function a webpage route you just need to add above that function @app.route("/greet")

@app.route("/greet")
def greet():
  return "Greetings"

You can access to what greet function returns with:

 127.0.0.1:8000/greet 

The name of route you specify inside route() is up to you.

Hope this help.
