介绍下其他方法如何用Python画一个圣诞树呢?
最简单:
height = 5stars = 1for i in range(height): print((' ' * (height - i)) + ('*' * stars)) stars += 2print((' ' * height) + '|')
效果:
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:
import turtle screen = turtle.Screen() screen.setup(800,600) 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 = 0for i in range(1, 17): 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 += 2 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(17,20): y = 30*i for j in range(3): x = 30*j square.goto(x,-y+280) square.stamp() square.goto(-x,-y+280) square.stamp()turtle.exitonclick()
