turtle.undobufferentries() function in Python

0 0 1 minute read

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.undobufferentries()

This function is used to return the count of entries in the undobuffer. It doesn’t require any argument.

Syntax :

turtle.undobufferentries()

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

Example 1 :

Python3

# import package 
import turtle 
  
# loop for motion 
for i in range(50): 
    turtle.forward(20+2*i) 
    turtle.right(90) 
  
# check the undo buffer size 
# it is loop iteration*turtle's statement 
# i.e; 50*2 = 100 
print(turtle.undobufferentries())

Output :

Example 2 :

Python3

# import package 
import turtle 
  
# loop for motion 
for i in range(50): 
    turtle.forward(20+2*i) 
    turtle.right(90) 
  
# call undo() method till the  
# undobuffer length 
while turtle.undobufferentries(): 
    turtle.undo()
