如何用Python画一个圣诞树呢?

最简单:

height = 5  stars = 1 for i in range(height):     print((' ' * (height - i)) + ('*' * stars))     stars += 2 print((' ' * height) + '|')

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:

 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()

方法二:

 from turtle import *  import random  import time   n = 80.0  speed("fastest")  screensize(bg='seashell')  left(90) forward(3*n) color("orange", "yellow") begin_fill() left(126) for i in range(5):     forward(n/5)     right(144)     forward(n/5)     left(72) end_fill() right(126)  color("dark green") backward(n*4.8) def tree(d, s):     if d <= 0: return     forward(s)     tree(d-1, s*.8)     right(120)     tree(d-3, s*.5)     right(120)     tree(d-3, s*.5)     right(120)     backward(s) tree(15, n) backward(n/2)  for i in range(200):     a = 200 - 400 * random.random()     b = 10 - 20 * random.random()     up()     forward(b)     left(90)     forward(a)     down()     if random.randint(0, 1) == 0:             color('tomato')     else:         color('wheat')     circle(2)     up()     backward(a)     right(90)     backward(b) time.sleep(60)
