Python – turtle.done()

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.done()

This function is used to starts event loop – calling Tkinter’s main loop function. It does not require any argument. Must be the last statement in a turtle graphics program. Must NOT be used if a script is run from within IDLE in -n mode (No subprocess) – for interactive use of turtle graphics.

Syntax : turtle.done() 
Parameters : None 
Returns : None 

Below is the implementation of the above method with some examples :

Example 1 : At the end.

python3

# import package
import turtle

# motion
turtle.forward(100)
turtle.right(90)
turtle.forward(100)

# stop execution
turtle.done()

Output :

Example 2 : Stop the execution at any step. 

python3

# import package
import turtle

# motion
turtle.circle(20)
turtle.circle(30)

# stop execution
turtle.done()

# motion
turtle.circle(40)
turtle.circle(50)

Output :
