使用python删除temp文件夹中的所有文件

问题描述

这是我的代码，用于删除临时文件夹中的所有文件，但是由于使用了临时文件，我想跳过所有无法删除的文件，并删除其余所有文件。谁能建议我更好的代码？

def del_tmp_files():
    username = getpass.getuser()
    del_path = "C:\\Users\\" + username + "\\AppData\\Local\\Temp"
    shutil.rmtree(del_path)
    print("Del Path" + del_path)
    return

解决方法

您可以实现try try框架来删除文件，这是伪代码：

cd temp directory
fileList = get all the filenames in the temp directory
for file in fileList:
  try:
    delete file
  except:
    pass

将 ignore_errors=True 与shutil.rmtree一起使用。

def rmtree(path,ignore_errors=False,onerror=None):

递归删除目录树。

If ignore_errors is set,errors are ignored; otherwise,if onerror
is set,it is called to handle the error with arguments (func,path,exc_info) where func is platform and implementation dependent;
path is the argument to that function that caused it to fail; and
exc_info is a tuple returned by sys.exc_info().  If ignore_errors
is false and onerror is None,an exception is raised.

import getpass
import shutil

def del_tmp_files():
    username = getpass.getuser()
    del_path = "C:\\Users\\" + username + "\\AppData\\Local\\Temp"
    shutil.rmtree(del_path,ignore_errors=True)
    print("Del Path" + del_path) 
    return

del_tmp_files()

python shutil
