用python画樱花树的代码(Python画一棵漂亮的樱花树)(1)

  • 实现代码
  • import turtle as T import random import time # 画樱花的躯干(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) # 6 t.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) # 绘图区域 t = T.Turtle() # 画布大小 w = T.Screen() t.hideturtle() # 隐藏画笔 t.getscreen().tracer(5, 0) w.screensize(bg='wheat') # wheat小麦 t.left(90) t.up() t.backward(150) t.down() t.color('sienna') # 画樱花的躯干 Tree(60, t) # 掉落的花瓣 Petal(200, t) w.exitonclick()
