python3 遍历文件

程序很简单，parent,dirnames,filenames分别表明当前目录下的文件夹数及文件数，然后通过os.wolk向深入遍历。

import os
import os.path

# this folder is custom
rootdir="G:\Download"
for parent,dirnames,filenames in os.walk(rootdir):
    #case 1:
    for dirname in dirnames:
        print("parent folder is:" + parent)
        print("dirname is:" + dirname)
    #case 2
    for filename in filenames:   
        print("parent folder is:" + parent)
        print("filename with full path:"+ os.path.join(parent,filename))
