        前言

        就是用python做一个简易的音乐播放器,废话不多说,咱们直接开干

        当然,今天做这个肯定不是最简单的,最简单的音乐播放器,9行代码足以

        import time
        import pygame
        
        file = r'歌曲路径'
        pygame.mixer.init()
        print('正在播放',file)
        track = pygame.mixer.music.load(file)
        pygame.mixer.music.play()
        time.sleep(130)
        pygame.mixer.music.stop()
