结果
介绍下其他方法如何用Python画一个圣诞树呢?
最简单:
stars = 1 for i in range(height): print((' ' * (height - i)) + ('*' * stars)) stars += 2 print((' ' * height) + '|')
效果:
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 = 0 for 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()
效果:
