Python turtle.done() (original) (raw)

Last Updated : 25 Aug, 2025

turtle.done() starts the event loop in Turtle graphics by calling Tkinter’s main loop. Placed at the end of a program, it keeps the window open and responsive. It takes no arguments and should not be used in IDLE’s -n (No subprocess) mode.

**Syntax

turtle.done()

• **Parameters : None
• **Returns : None

Examples

**Example 1 : At the end.

python `

import turtle

simple motion

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

stop execution and keep window open

turtle.done()

`

**Output :

**Explanation: The turtle moves forward 100 units, turns 90°, moves another 100 units, and then **turtle.done() keeps the window open so the user can view the drawing.

**Example 2 : Stop the execution at any step.

python `

import turtle

some motions

turtle.circle(20) turtle.circle(30)

stop execution

turtle.done()

further motions (will not execute)

turtle.circle(40) turtle.circle(50)

`

**Output :

**Explanation: After **turtle.done(), the turtle graphics program stops execution. Any code written after **turtle.done() will not run, ensuring the drawing window stays open without further motion.
