哈哈哈哈，总有一种骗了大家的感觉。
其实本文是想介绍Turtle库来画圣诞树。
方法一：

1import turtle 2screen = turtle.Screen() 3screen.setup(800,600) 4circle = turtle.Turtle() 5circle.shape('circle') 6circle.color('red') 7circle.speed('fastest') 8circle.up() 9square = turtle.Turtle() 10square.shape('square') 11square.color('green') 12square.speed('fastest') 13square.up() 14circle.goto(0,280) 15circle.stamp() 16k = 0 17for i in range(1, 17): 18y = 30*i 19for j in range(i-k): 20x = 30*j 21square.goto(x,-y+280) 22square.stamp() 23square.goto(-x,-y+280) 24square.stamp() 25if i % 4 == 0: 26x = 30*(j+1) 27circle.color('red') 28circle.goto(-x,-y+280) 29circle.stamp() 30circle.goto(x,-y+280) 31circle.stamp() 32k += 2 33if i % 4 == 3: 34x = 30*(j+1) 35circle.color('yellow') 36circle.goto(-x,-y+280) 37circle.stamp() 38circle.goto(x,-y+280) 39circle.stamp() 40square.color('brown') 41for i in range(17,20): 42y = 30*i 43for j in range(3): 44x = 30*j 45square.goto(x,-y+280) 46square.stamp() 47square.goto(-x,-y+280) 48square.stamp() 49turtle.exitonclick()
