turtle.ontimer()
This function is used to install a timer, which calls fun after t milliseconds.
Syntax :
turtle.ontimer(fun, t=0)
Parameters:
| Arguments | Description |
| fun | a function with no arguments |
| t | a number >= 0 |
Below is the implementation of the above method with an example :
Python3
# import packages import turtle import random # global colors col = ['red', 'yellow', 'green', 'blue', 'white', 'black', 'orange', 'pink'] # method to call on timer def fxn(): global col ind = random.randint(0, 7) # set background color of the # turtle screen randomly sc.bgcolor(col[ind]) # set screen sc = turtle.Screen() sc.setup(400, 300) # loop for timer for i in range(10): turtle.ontimer(fxn, t=400*(i+1)) |
Output :
Here we can find that after some time (set by timer) it automatically changes the background color of the turtle graphics window randomly.
turtle.ontimer() function in Python
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.
