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 :
1
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 )
