遍历文件夹

import os  #载入操作系统模块，用于文件及文件夹操作
import sys #载入系统模块
import io  #载入读写模块
sys.stdout = io.TextIOWrapper(sys.stdout.buffer,encoding="utf-8")  #标准输出（sys.stdout）设置为UTF-8编码
for foldername,subfolders,filenames in os.walk("f:\\python"):       #遍历f:\\python文件夹
    print("The current folder is " + foldername)                   #当前文件夹
    for subfolders in subfolders:                                     #遍历子文件夹
        print("SUBFOLDER OF " + foldername + "\\" + subfolders)
    for filenames in filenames:                                        #遍历文件
        print("FILE INSID " + foldername + "\\" + filenames)
    print("")
