Python随机播放音乐的代码详解编程语言

就是找到硬盘中所有的MP3文件和wma文件，再随机打开其中的一个。

    import os,random   
    disk=['D','E','F','G','H']

            candidate = os.path.join(path,filename)   
            if os.path.isfile(candidate):   
                return os.path.abspath(candidate)   
    def random_play():   
        music=[]   
        found=False
