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 :
# importing package
import turtle
# check default value
print(turtle.tracer())
Output :
1
Example 2 :
# 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)
Output :
