turtle.speed() 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.

turtle.speed()

The turtle.speed() method is used to change the speed of the turtle by the value of the argument that it takes. Return or set the turtle’s speed.

Syntax :

turtle.speed(speed=None)

Note:

• The turtle’s speed lies in the range 0-10.
• If input is a number greater than 10 or smaller than 0.5, speed is set to 0.
• Speedstrings  are mapped to speedvalues in the following way:
  • ‘fastest’ :  0
  • ‘fast’    :  10
  • ‘normal’  :  6
  • ‘slow’    :  3
  • ‘slowest’ :  1
• Speeds from 1 to 10 enforce increasingly faster animation of line drawing and turtle turning.

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

Example 1 :

Python3

# import package
import turtle

# slowest speed
turtle.speed(1)

# turtle movement
turtle.forward(150)

Output :

Example 2 :

Python3

# import package
import turtle

# loop for pattern
for i in range(10):

  # set turtle speed
  turtle.speed(10-i)

  # motion for pattern
  turtle.forward(50+10*i)
  turtle.right(90)

Output :
