turtle.screensize() 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.screensize()

This method is used to resize the canvas the turtles are drawing on. If no arguments are given, this function returns the current (canvaswidth, canvasheight).

Syntax :

turtle.screensize(canvwidth=None, canvheight=None, bg=None)

Parameters:

Arguments	Value	Description
canvwidth	positive integer	new width of canvas in pixels
canvheight	positive integer	new height of canvas in pixels
bg	colorstring or color-tuple	new backgroundcolor

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

Example 1 :

Python3

# import package
import turtle


# check the screensize by default
# it varies ide to ide
print(turtle.screensize())

Output :

(400, 300)

Example 2 :

Python3

# import package
import turtle


# set screen
turtle.screensize(canvwidth=400, canvheight=400,
                  bg="yellow")

Output :

Example 3 :

Python3

# import package
import turtle

# set turtle
turtle.width(2)
turtle.speed(10)

# loop for pattern
for i in range(10):
    turtle.circle(40)
    turtle.right(36)

# set screen and drawing remain as it is.
turtle.screensize(canvwidth=400, canvheight=300,
                  bg="blue")

Output :
