import turtle screen = turtle.Screen() screen.setup(375, 700) circle = turtle.Turtle() circle.shape('circle') circle.color('red') circle.speed('fastest') circle.up() square = turtle.Turtle() square.shape('square') square.color('green') square.speed('fastest') square.up() circle.goto(0, 280) circle.stamp() k = 0 for i in range(1, 13):    y = 30 * i    for j in range(i - k):        x = 30 * j        square.goto(x, -y + 280)        square.stamp()        square.goto(-x, -y + 280)        square.stamp() if i % 4 == 0:    x = 30 * (j + 1)    circle.color('red')    circle.goto(-x, -y + 280)    circle.stamp()    circle.goto(x, -y + 280)    circle.stamp()    k += 3 if i % 4 == 3:    x = 30 * (j + 1)    circle.color('yellow')    circle.goto(-x, -y + 280)    circle.stamp()    circle.goto(x, -y + 280)    circle.stamp() square.color('brown') for i in range(13, 17):    y = 30 * i    for j in range(2):        x = 30 * j        square.goto(x, -y + 280)        square.stamp()        square.goto(-x, -y + 280)        square.stamp()
