Question

我无法想出一种安全删除提供的根目录中除最近创建或更新的文件夹之外的所有文件夹的方法。我有这个基本的结构设置，但我不知道如何从这里开始：

for root, folders, files in os.walk(output_folder):
    for folder in folders:

Answer 1

你可以找到像这样的最新文件夹

import os, shutil

newest_folder = max(folders, key=os.path.getmtime)

for fname in folders:
    if fname != newest_folder:
        shutil.rmtree(folder)

根据您的具体要求，您可能希望使用getctime代替getmtime

Answer 2

这可能适合您： -

import os
import datetime as dt
import shutil


now = dt.datetime.now()
ago = now-dt.timedelta(minutes=30) #Mention the required time

for root, dirs,files in os.walk('/home/piyush/pppptest'): #put required directory path
    for fname in files:
        path = os.path.join(root, fname)
        st = os.stat(path)    
        mtime = dt.datetime.fromtimestamp(st.st_mtime) #Gives you the modified time of file
        # print mtime
        if mtime > ago:
            print('%s modified %s'%(path, mtime)) #You can check path and modified and work on it as per your requirement
            shutil.rmtree('path') #You can delete it.

删除Python中除最新文件夹外的所有文件夹
