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 :
# 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 :
100
Example 2 :
# 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()
Output :
