python - Getting the widget that triggered an Event?

Question

In Tkinter, I have a multiple widgets bound to the left-mouse button. They all trigger the same event when clicked.

How do I recover which widget was clicked?

I want it so when say Label2 was pressed, I'd be able to recover that Label2 was the widget that was pressed within the event it triggered.

Answer 1

def f(event):
    caller = event.widget
