Archery Target
With the help of a loop, simulate an archery target. Use a variable to hold the initial radius.
Now it's your turn. Fill in the missing pieces below to align the circles!
import turtle
import random
circles = 5
radius = 20
delta = 20
size =20
for i in range(circles):
t = turtle.Turtle()
t.speed(50)
t.pensize(size)
t.color(random.randrange(256), random.randrange(256), random.randrange(256))
t.up()
# fill in here
# fill in here
# fill in here
t.down()
t.circle(radius + i*delta)
t.hideturtle()
