The binding function is used to handle events. We can tie Python’s functions and methods to an event as well as any specific widget.

Example:

from tkinter import *

from tkinter.ttk import *

# creates tkinter window or root window

ws = Tk()

ws.geometry('200x100')

def enter(event):

    print('Button-2 pressed at x = % d, y = % d'%(event.x, event.y))

def exit_(event):

    print('Button-3 pressed at x = % d, y = % d'%(event.x, event.y))

frame_1 = Frame(ws, height = 100, width = 200)

frame_1.bind('', enter)

frame_1.bind('', exit_) 

frame_1.pack() 

ws.mainloop()
