怎么用python画圣诞树(python,开发技术)

如何用python画一个圣诞树呢？
Turtle库来画圣诞树。

1.方块圣诞树

importturtlescreen=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=0foriinrange(1,13):y=30*iforjinrange(i-k):x=30*jsquare.goto(x,-y+280)square.stamp()square.goto(-x,-y+280)square.stamp()ifi%4==0:x=30*(j+1)circle.color('red')circle.goto(-x,-y+280)circle.stamp()circle.goto(x,-y+280)circle.stamp()k+=3ifi%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')foriinrange(13,17):y=30*iforjinrange(2):x=30*jsquare.goto(x,-y+280)square.stamp()square.goto(-x,-y+280)square.stamp()

2.线条圣诞树

importturtle#定义圣诞树的绿叶函数deftree(d,s):ifd<=0:returnturtle.forward(s)tree(d-1,s*.8)turtle.right(120)tree(d-3,s*.5)turtle.right(120)tree(d-3,s*.5)turtle.right(120)turtle.backward(s)n=100"""设置绘图速度'fastest':0'fast':10'normal':6'slow':3'slowest':1"""turtle.speed('fastest')#设置速度turtle.left(90)turtle.forward(3*n)turtle.color("orange","yellow")turtle.left(126)#turtle.begin_fill()foriinrange(5):turtle.forward(n/5)turtle.right(144)turtle.forward(n/5)turtle.left(72)turtle.end_fill()turtle.right(126)turtle.color("darkgreen")turtle.backward(n*4.8)#执行函数tree(15,n)turtle.backward(n/5)

3.豪华圣诞树
