例子，遍歷目錄下文件

def search(folder, filter, allfile):
    folders = os.listdir(folder)
    for name in folders:
        curname = os.path.join(folder, name)
        isfile = os.path.isfile(curname)

                cur.name = curname
                allfile.append(cur)
        else:
            search(curname, filter, allfile)
    return allfile
 

例子

遍歷文件夾並刪除特定格式文件

#!/usr/bin/python
# -*- coding: utf-8 -*-

import os

def del_files(path):
    for root , dirs, files in os.walk(path):
        for name in files:
            if name.endswith(".tmp"):
                os.remove(os.path.join(root, name))
  print ("Delete File: " + os.path.join(root, name))

# test
if __name__ == "__main__":
    path = '/tmp'
    del_files(path)
