turtle.onscreenclick()
This function is used to bind fun to a mouse-click event on canvas.
Syntax :
turtle.onscreenclick(fun, btn=1, add=None)
Parameters:
| Arguments | Description |
| fun | a function with two arguments, the coordinates of the clicked point on the canvas. |
| btn | number of the mouse-button defaults to 1 (left mouse button) |
| add | True or False. If True, new binding will be added, otherwise it will replace a former binding |
Below is the implementation of the above method with an example :
Python3
# import packages import turtle import random # global colors col = ['red', 'yellow', 'green', 'blue', 'white', 'black', 'orange', 'pink'] # method to call on screen click def fxn(x, y): global col ind = random.randint(0, 7) # set screen color randomly sc.bgcolor(col[ind]) # set screen sc = turtle.Screen() sc.setup(400, 300) # call method on screen click turtle.onscreenclick(fxn) |
Output :
Here we can find that whenever the user clicks (yellow-colored dot on arrow) on screen it changes the background color of the turtle graphics window randomly.

The turtle module provides turtle graphics primitives, in both object-oriented and procedure-oriented ways. Because it uses Tkinter for the underlying graphics, it needs a version of Python installed with Tk support.
