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 :
100
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() |
Output :
