最近用Python（大多是turtle庫）繪制的櫻花樹有點火，感覺很漂亮，我整理了一下，挑了一些我覺得不錯的代碼分享給大家（這些我都測試過，確實可以生成喔~）
one 櫻花樹

（一) 動態(tài)生成櫻花
效果圖（這個是動態(tài)的）：

實現(xiàn)代碼

import turtle as T import random import time# 畫櫻花的軀干(60,t) def Tree(branch, t):time.sleep(0.0005)if branch > 3:if 8 <= branch <= 12:if random.randint(0, 2) == 0:t.color('snow') # 白else:t.color('lightcoral') # 淡珊瑚色t.pensize(branch / 3)elif branch < 8:if random.randint(0, 1) == 0:t.color('snow')else:t.color('lightcoral') # 淡珊瑚色t.pensize(branch / 2)else:t.color('sienna') # 赭(zhě)色t.pensize(branch / 10) # 6t.forward(branch)a = 1.5 * random.random()t.right(20 * a)b = 1.5 * random.random()Tree(branch - 10 * b, t)t.left(40 * a)Tree(branch - 10 * b, t)t.right(20 * a)t.up()t.backward(branch)t.down()# 掉落的花瓣 def Petal(m, t):for i in range(m):a = 200 - 400 * random.random()b = 10 - 20 * random.random()t.up()t.forward(b)t.left(90)t.forward(a)t.down()t.color('lightcoral') # 淡珊瑚色t.circle(1)t.up()t.backward(a)t.right(90)t.backward(b)# 繪圖區(qū)域 t = T.Turtle() # 畫布大小 w = T.Screen() t.hideturtle() # 隱藏畫筆 t.getscreen().tracer(5, 0) w.screensize(bg='wheat') # wheat小麥 t.left(90) t.up() t.backward(150) t.down() t.color('sienna')# 畫櫻花的軀干 Tree(60, t) # 掉落的花瓣 Petal(200, t) w.exitonclick()

（二）飄落效果
