The program is an illustration of loops and functions
Functions are named program statements that are executed when called or evoked
Loops are program statements that are used to perform repetition operations
The program written in Python, where comments are used to explain the lines is as follows:
#This sets the speed of the turtle to 0
speed(0)
#This function draws the bead
def draw_bead():
penup()
forward(100)
pendown()
circle(10)
penup()
backward(100)
#This loop is repeated 36 times
for i in range(36):
draw_bead()
left(10)
