python代码画动态樱花

动态樱花可以使用Python的turtle库来实现。下面是一个简单的示例代码：

import turtle
import random

# 设置画布大小和背景颜色
turtle.setup(800, 600)
turtle.bgcolor('pink')

# 定义樱花的形状
def sakura():
    turtle.begin_fill()
    turtle.circle(10, 180)
    turtle.circle(25, 110)
    turtle.left(50)
    turtle.circle(60, 45)
    turtle.circle(20, 170)
    turtle.right(24)
    turtle.fd(30)
    turtle.left(10)
    turtle.circle(30, 110)
    turtle.fd(20)
    turtle.left(40)
    turtle.circle(90, 70)
    turtle.circle(30, 150)
    turtle.right(30)
    turtle.fd(15)
    turtle.circle(80, 90)
    turtle.left(15)
    turtle.fd(45)
    turtle.right(165)
    turtle.fd(20)
    turtle.left(155)
    turtle.circle(150, 80)
    turtle.left(50)
    turtle.circle(150, 90)
    turtle.end_fill()

# 定义花瓣飘落的动画
def petal_fall(petal, speed):
    petal.penup()
    petal.goto(random.randint(-350, 350), 250)
    petal.pendown()
    while petal.ycor() > -300:
        x = petal.xcor() - random.randint(-5, 5)
        y = petal.ycor() - speed
        petal.goto(x, y)

# 画出樱花树
trunk = turtle.Turtle()
trunk.hideturtle()
trunk.speed(0)
trunk.penup()
trunk.goto(0, -200)
trunk.pendown()
trunk.color('brown')
trunk.pensize(30)
trunk.left(90)
trunk.fd(200)
trunk.right(180)
trunk.fd(400)

# 画出樱花
petals = []
for i in range(50):
    petal = turtle.Turtle()
    petal.hideturtle()
    petal.speed(0)
    petal.color('pink')
    petal.pensize(1)
    petal.left(random.randint(0, 360))
    sakura()
    petals.append(petal)

# 花瓣飘落
while True:
    for petal in petals:
        petal_fall(petal, random.randint(1, 5))
