分享給大家一篇文章,教你怎樣用Python畫了一棵聖誕樹,快來學習。
如何用Python畫一個聖誕樹呢?
最簡單:
height = 5 stars = 1 for i in range(height): print((' ' * (height - i)) + ('*' * stars)) stars += 2 print((' ' * 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 turtle screen = 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 = 0 for 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() 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()
效果:
方法二:
import turtle # 定義聖誕樹的綠葉函式 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) # 執行函式 tree(15,n) turtle.backward(n / 5)
