Question

write a non pure function (procedure) named drawstar that atkes no arguments and draws a 5 pointed star using python turtle graphics :

the drawsar procedure should do the following :

open a turtle dialogue box and have the user enter the length of each side.

draw a five pointed star with each side length as entered by the user. (hint: the internal angle of each points is 36 degrees)

to be honest, i really want to know how to do this on my own so if anybody could guide me it would be great. I am really stuck on the difference between pure function and non pure functions and also assign the side length to the user input box, which is the turtle.numinput() command i believe. PLEASE help and please try to explain..

Answer 1

Answer

#using turtle graphics , draw the five point star without lines inside

#import turtle module

import turtle

#definition of Star for draw the star without

#inside lines

def Star(size):

    #angle define

    angle =120

    #for five sides

    for eachside in range(5):

        #forward direction

        turtle.forward(size)

        #right side

        turtle.right(angle)

        #forward direction

        turtle.forward(size)

        #right side

        turtle.right (72-angle)

    return

#method call here

#size passed through the method

Star(100)
