Remove all files in a directory

问题

Trying to remove all of the files in a certain directory gives me the follwing error:

OSError: [Errno 2] No such file or directory: '/home/me/test/*'

The code I'm running is:

import os
test = "/home/me/test/*"
os.remove(test)

回答1:

os.remove() does not work on a directory, and os.rmdir() will only work on an empty directory. And Python won't automatically expand "/home/me/test/*" like some shells do.

You can use shutil.rmtree() on the directory to do this, however.

import shutil
shutil.rmtree('/home/me/test')

be careful as it removes the files and the sub-directories as well.

回答2:

os.remove doesn't resolve unix-style patterns. If you are on a unix-like system you can:

os.system('rm '+test)

Else you can:

import glob, os
test = '/path/*'
r = glob.glob(test)
for i in r:
   os.remove(i)

回答3:

Because the * is a shell construct. Python is literally looking for a file named "*" in the directory /home/me/test. Use listdir to get a list of the files first and then call remove on each one.

Although this is an old question, I think none has already answered using this approach:

# python 2.7
import os

d='/home/me/test'
filesToRemove = [os.path.join(d,f) for f in os.listdir(d)]
for f in filesToRemove:
    os.remove(f)

star is expanded by Unix shell. Your call is not accessing shell, it's merely trying to remove a file with the name ending with the star

shutil.rmtree() for most cases. But it doesn't work for in Windows for readonly files. For windows import win32api and win32con modules from PyWin32.

def rmtree(dirname):
    retry = True
    while retry:
        retry = False
        try:
            shutil.rmtree(dirname)
        except exceptions.WindowsError, e:
            if e.winerror == 5: # No write permission
                win32api.SetFileAttributes(dirname, win32con.FILE_ATTRIBUTE_NORMAL)
                retry = True

Another way I've done this:

os.popen('rm -f ./yourdir')

回答8:

This will get all files in a directory and remove them.

import os

BASE_DIR = os.path.dirname(os.path.abspath(__file__))
dir = os.path.join(BASE_DIR, "foldername")

for root, dirs, files in os.walk(dir):
  for file in files:
    path = os.path.join(dir, file)
    os.remove(path)

回答9:

Bit of a hack but if you would like to keep the directory, the following can be used.

import os
import shutil
shutil.rmtree('/home/me/test') 
os.mkdir('/home/me/test')

回答10:

os.remove will only remove a single file.

In order to remove with wildcards, you'll need to write your own routine that handles this.

There are quite a few suggested approaches listed on this forum page.

It's a long and ugly, but reliable and efficient solution.

It resolves a few problems which are not addressed by the other answerers:

It correctly handles symbolic links, including not calling shutil.rmtree() on a symbolic link (which will pass the os.path.isdir() test if it links to a directory).
It handles read-only files nicely.

#python 2.7
import tempfile
import shutil
import exceptions
import os

def TempCleaner():
    temp_dir_name = tempfile.gettempdir()
    for currentdir in os.listdir(temp_dir_name):
        try:
           shutil.rmtree(os.path.join(temp_dir_name, currentdir))
        except exceptions.WindowsError, e:
            print u'Не удалось удалить:'+ e.filename
