one 樱花树

动态生成樱花

效果图（这个是动态的）：

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()
