‘‘‘os.walk方法os模块提供的walk方法很强大，能够把给定的目录下的所有目录和文件遍历出来。方法：os.walk(path),遍历path，返回一个对象，他的每个部分都是一个三元组,(‘目录x‘，[目录x下的目录list]，目录x下面的文件)‘‘‘import osdef walk_dir(dir,fileinfo,topdown=True):    for root, dirs, files in os.walk(dir, topdown):        for name in files:            print(os.path.join(name))            fileinfo.write(os.path.join(root,name) + ‘\n‘)        for name in dirs:            print(os.path.join(name))            fileinfo.write(‘  ‘ + os.path.join(root,name) + ‘\n‘)dir = raw_input(‘please input the path:‘)fileinfo = open(‘list.txt‘,‘w‘)walk_dir(dir,fileinfo)‘‘‘topdown决定遍历的顺序，如果topdown为True，则先列举top下的目录，然后是目录的目录，依次类推，反之，则先递归列举出最深层的子目录，然后是其兄弟目录，然后子目录。‘‘‘
