在python中查找最近编辑的文件 [英] Finding most recently edited file in python

问题描述

我有一组文件夹，并且我希望能够运行一个功能，该功能可以找到最近编辑的文件，并告诉我文件名和它所在的文件夹.

I have a set of folders, and I want to be able to run a function that will find the most recently edited file and tell me the name of the file and the folder it is in.

文件夹布局:

root
    Folder A
        File A
        File B
    Folder B
        File C
        File D
etc...

任何碰壁的技巧都可以帮助我入门.

Any tips to get me started as i've hit a bit of a wall.

推荐答案

您应该查看操作系统. walk 函数以及 os.stat ，它可以让您执行某些操作像:

You should look at the os.walk function, as well as os.stat, which can let you do something like:

import os

max_mtime = 0
for dirname,subdirs,files in os.walk("."):
    for fname in files:
        full_path = os.path.join(dirname, fname)
        mtime = os.stat(full_path).st_mtime
        if mtime > max_mtime:
            max_mtime = mtime
            max_dir = dirname
            max_file = fname

print max_dir, max_file
