turtle.tracer() 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.tracer()

This function is used to turn turtle animation on or off and set a delay for update drawings.

Syntax : turtle.tracer(n=None, delay=None)

Parameters:

n: If n is given, only each n-th regular screen update is really performed.

delay: sets delay value

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

Example 1 :

Python3

# importing package 
import turtle 
  
# check default value 
print(turtle.tracer())

Output :

Example 2 :

Python3

# importing package 
import turtle 
  
# loop for motion with 
# default tracer as 1 
for i in range(20): 
    turtle.forward(1+1*i) 
    turtle.right(45) 
  
# set tracer values as (2,0) 
# 2 -> for screen update 
# 0 -> delay 
turtle.tracer(n=2, delay=0) 
  
# loop for motion with 
# above tracer values 
for i in range(20, 40): 
    turtle.forward(1+1*i) 
    turtle.right(45) 
  
# set tracer values as (1,50) 
# 1 -> for screen update 
# 50 -> delay 
turtle.tracer(n=1, delay=50) 
  
# loop for motion with 
# above tracer values 
for i in range(40, 60): 
    turtle.forward(1+1*i) 
    turtle.right(45)
