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) |
