python中动态爱心代码

以下是基于Python实现动态漂浮爱心的源码：

import random as ra
import math
import os
import time

class Heart():
    #每个爱心（爱心类）
    def __init__(self):
        self.r = ra.randint(10,15) #爱心的半径
        self.x = ra.randint(-1000,1000) #爱心的横坐标
        self.y = ra.randint(-1000,1000) #爱心的纵坐标
        self.color = (ra.randint(100,255),ra.randint(100,255),ra.randint(100,255)) #爱心的颜色

    def draw(self,canvas):
        #绘制爱心
        for i in range(360):
            x = self.r*math.sin(math.radians(i))*math.sin(math.radians(i))*math.sin(math.radians(i))
            y = self.r*math.cos(math.radians(i))*math.cos(math.radians(i))*math.cos(math.radians(i))
            canvas.set_at((int(self.x+x),int(self.y-y)),self.color)

class HeartWall():
    #爱心墙（爱心墙类）
    def __init__(self):
        self.hearts = []
        self.num = 100 #爱心的数量
        self.screen = None

    def create(self):
        #创建爱心
        for i in range(self.num):
            self.hearts.append(Heart())

    def draw(self):
        #绘制爱心
        for heart in self.hearts:
            heart.draw(self.screen)

    def move(self):
        #移动爱心
        for heart in self.hearts:
            heart.y += 1
            if heart.y > 1000:
                heart.y = -1000
    def run(self):
        #运行爱心墙
        os.environ['SDL_VIDEO_WINDOW_POS'] = "%d,%d" % (300,100) #设置窗口位置
        os.environ['SDL_VIDEO_CENTERED'] = '0' #窗口居中
        os.environ['SDL_AUDIODRIVER'] = 'dsp' #音频驱动
        import pygame
        pygame.init()
        self.screen = pygame.display.set_mode((2000,1000))
        pygame.display.set_caption("Heart Wall")
        self.create()
        while True:
            for event in pygame.event.get():
                if event.type == pygame.QUIT:
                    pygame.quit()
                    exit()
            self.screen.fill((0,0,0))
            self.draw()
            self.move()
            pygame.display.update()
            time.sleep(0.01)

heart_wall = HeartWall()
heart_wall.run()
