Question

2) Write a Python program that draw simple lollipop (a line and few circles, the line should attach to the circles, just as regular lollipop, you decide the colors), just as we make a "dart" for assignment. You can use the same idea when we make "target" by making few circles with different colors, and using mouse click get 2 points to draw a line.

See sample program from Zelle textbook, chapter 4, click.pyw and triangle.pyw. Or see assignment archery.pyw.

Make sure to save this program inside the folder, where the graphics.py is saved, since we need to import graphics.py on top of the program.

Answer 1

I am putting 4 codes here with little variations. You can use the one which suits you the best or you can edit them to meet your requirement,

[1]

import turtle
t=turtle.Turtle()
t.penup()
flag=0
#the initial radius of the circle will be 100 which will keep on decreasing by
#20 after each iteration, there will be total 5 iterations.
for i in range(100, 1, -20):
t.right(90) # Face South
t.forward(i) # Move one radius
t.right(270) # Back to start heading
t.pendown() # Put the pen back down
# choosing two random colors
if(flag==0):
t.fillcolor('pink')
flag=1
else:
t.fillcolor('red')
flag=0
t.begin_fill()
t.circle(i)
t.end_fill()
#t.circle(i) # Draw a circle
t.penup() # Pen up while we go home
t.home()

t.pendown()
t.pensize("10")
t.pencolor('blue')
t.right(90)
t.forward(250)

OUTPUT
