The turtle.undobufferentries() function returns the number of entries in the undo buffer. The undo buffer stores actions that can be reversed with undo().

Syntax: turtle.undobufferentries()
Parameters: None.

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

Demo62.py

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

import turtle

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

t.forward(100)
t.left(90)
t.forward(50)

# Get number of undo buffer entries
entries = t.undobufferentries()
print("Undo buffer entries:", entries)

window.exitonclick()

The following is the output:

turtle.undobufferentries() function in Python

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.
Move forward:forward(100) draws a 100-unit line (pen down by default).
Turn left:left(90) rotates the turtle 90° counterclockwise.
Move forward again:forward(50) draws another line in the new direction.
Get undo buffer entries: entries = t.undobufferentries() returns how many actions are currently stored in this turtle’s undo buffer (each move/turn typically adds entries).
Print entries: print(“Undo buffer entries:”, entries) outputs the count to the console.
Close on click:exitonclick() waits for a mouse click, then closes the window.
