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.register_shape()
This function is used to add a turtle shape to TurtleScreen's shapelist.
Syntax :
turtle.register_shape(name, shape=None)
Parameters:
| Arguments | Description |
| name | string |
| shape | tuple of pairs of coordinates |
Below is the implementation of the above method with an example :
# import package
import turtle
# record a polygon
turtle.begin_poly()
# form a polygon
turtle.seth(-45)
turtle.circle(20, 90)
turtle.circle(10, 90)
turtle.circle(20, 90)
turtle.circle(10, 90)
turtle.end_poly()
# get polygon
pairs = turtle.get_poly()
# register shape with
# name : new_shape
# polygon : pairs
turtle.register_shape("new_shape", pairs)
# clear screen
turtle.clearscreen()
# use new shape and
# apply properties
turtle.shape("new_shape")
turtle.fillcolor("blue")
# do some motion
for i in range(50):
turtle.forward(5+2*i)
turtle.right(45)
Output :
