python粒子爱心动态代码

以下是一个使用Python实现的粒子爱心动态代码：

import turtle
import random

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

# 定义粒子类
class Particle(turtle.Turtle):
    def __init__(self):
        turtle.Turtle.__init__(self, shape='circle')
        self.penup()
        self.speed(0)
        self.color(random.uniform(0, 1), random.uniform(0, 1), random.uniform(0, 1))
        self.goto(0, 0)
        self.direction = random.uniform(0, 360)
        self.velocity = random.uniform(1, 10)
        self.gravity = 0.1

    def move(self):
        self.goto(self.xcor() + self.velocity * math.cos(math.radians(self.direction)),
                  self.ycor() + self.velocity * math.sin(math.radians(self.direction)))
        self.velocity -= self.gravity

# 创建粒子列表
particles = []
for i in range(50):
    particles.append(Particle())

# 动画循环
while True:
    for particle in particles:
        particle.move()
        if particle.ycor() < -300:
            particle.goto(0, 0)
            particle.velocity = random.uniform(1, 10)
            particle.direction = random.uniform(0, 360)

    turtle.update()
