turtle.onrelease() function in Python

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.

turtle.onrelease()

This function is used to bind fun to the mouse-button-release event on this turtle on canvas.

Syntax :

turtle.onrelease(fun, btn=1, add=None) 

Parameters:

Below is the implementation of the above method with an example :

# import package import turtle # methods to action def fxn1(x,y): turtle.fillcolor("blue") def fxn2(x,y): turtle.fillcolor("white") # set screen and turtle sc=turtle.Screen() sc.setup(400,300) turtle.shape("turtle") turtle.turtlesize(2) turtle.speed(1) # allow user to click for some action turtle.onclick(fxn1) # allow user to release for some action turtle.onrelease(fxn2) 

Output :

Here we can find that :

• whenever the user click (yellow-colored dot on  arrow) on turtle it changes to the blue color, and
• after releasing (yellow dot disappears) from the screen it changes to white color.
