21 Sep turtle.resizemode() function in Python

The turtle.resizemodel() function sets the mode for resizing the turtle: “auto”, “user”, or “noresize”. Affects how turtlesize() behaves.

Syntax: turtle.resizemode(rmode=None)
Parameters: rmode – one of the strings “auto”, “user”, or “noresize”.

Let us see an example to implement the turtle.resizemode() function in Python:

Demo47.py

# turtle.resizemode() function in Python
# Code by Studyopedia

import turtle

window = turtle.Screen()
t = turtle.Turtle()

# Set resize mode: "auto", "user", or "noresize"
t.resizemode("auto")
t.turtlesize(2, 3)  # Will scale with pen size

window.exitonclick()

The following is the output:

In the above code, we followed the below steps:

• Import module: import turtle loads the turtle graphics library.
• Create screen: window = turtle.Screen() opens the drawing window.
• Create turtle: t = turtle.Turtle() creates the turtle you’ll control.
• Set resize mode (auto): t.resizemode(“auto”) makes the turtle’s displayed size automatically follow the current pen size. User-defined stretching via turtlesize is ignored in this mode; change with t.pensize(…) to see size updates.
• Set turtlesize: t.turtlesize(2, 3) assigns stretch factors (width=2, length=3), but in “auto” mode this has no visible effect. These values will apply only if you switch to t.resizemode(“user”).
• Close on click: window.exitonclick() waits for a mouse click, then closes the window.
