如何用Python畫一個聖誕樹呢？
最簡單的方法：
height = 5stars = 1for i in range(height): print((' ' * (height - i)) + ('*' * stars)) stars += 2print((' ' * height) + '|')
效果：
哈哈哈哈，總有一種騙了大家的感覺。
其實本文是想介紹Turtle庫來畫聖誕樹。
import turtlescreen = 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 = 0for i in range(1, 13): 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 += 3 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(13, 17): y = 30 * i for j in range(2): x = 30 * j square.goto(x, -y + 280) square.stamp() square.goto(-x, -y + 280) square.stamp()
效果：
方法二：
import turtle# 定義聖誕樹的綠葉函數def tree(d, s): if d <= 0: return turtle.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""" 設定繪圖速度'fastest' : 0'fast' : 10'normal' : 6'slow' : 3'slowest' : 1"""turtle.speed('fastest') # 設定速度turtle.left(90)turtle.forward(3 * n)turtle.color("orange", "yellow")turtle.left(126)# turtle.begin_fill()for i in range(5): turtle.forward(n / 5) turtle.right(144) turtle.forward(n / 5) turtle.left(72) turtle.end_fill()turtle.right(126)turtle.color("dark green")turtle.backward(n * 4.8)# 執行函數tree(15, n)turtle.backward(n / 5)
