当我试图删除一个非空文件夹时,我得到一个“访问被拒绝”错误。我在尝试中使用了以下命令:os.remove("/folder_name")。

删除一个非空文件夹/目录最有效的方法是什么?

来自os.walk()的python文档:

# Delete everything reachable from the directory named in 'top',
# assuming there are no symbolic links.
# CAUTION:  This is dangerous!  For example, if top == '/', it
# could delete all your disk files.
import os
for root, dirs, files in os.walk(top, topdown=False):
    for name in files:
        os.remove(os.path.join(root, name))
    for name in dirs:
        os.rmdir(os.path.join(root, name))

其他回答

import shutil

shutil.rmtree('/folder_name')

标准库参考:shutil.rmtree。

根据设计,rmtree在包含只读文件的文件夹树上失败。如果您希望删除文件夹而不管它是否包含只读文件,请使用

shutil.rmtree('/folder_name', ignore_errors=True)
import shutil
shutil.rmtree(dest, ignore_errors=True)

删除一个文件夹,即使它可能不存在(避免Charles Chow回答中的竞态条件),但当其他事情出错时仍然有错误(例如权限问题,磁盘读取错误,文件不是目录)

对于Python 3.x:

import shutil

def ignore_absent_file(func, path, exc_inf):
    except_instance = exc_inf[1]
    if isinstance(except_instance, FileNotFoundError):
        return
    raise except_instance

shutil.rmtree(dir_to_delete, onerror=ignore_absent_file)

Python 2.7的代码几乎是一样的:

import shutil
import errno

def ignore_absent_file(func, path, exc_inf):
    except_instance = exc_inf[1]
    if isinstance(except_instance, OSError) and \
        except_instance.errno == errno.ENOENT:
        return
    raise except_instance

shutil.rmtree(dir_to_delete, onerror=ignore_absent_file)

来自os.walk()的python文档:

# Delete everything reachable from the directory named in 'top',
# assuming there are no symbolic links.
# CAUTION:  This is dangerous!  For example, if top == '/', it
# could delete all your disk files.
import os
for root, dirs, files in os.walk(top, topdown=False):
    for name in files:
        os.remove(os.path.join(root, name))
    for name in dirs:
        os.rmdir(os.path.join(root, name))

只需一些python 3.5选项就可以完成上面的回答。(我很想在这里找到它们)。

import os
import shutil
from send2trash import send2trash # (shutil delete permanently)

删除空文件夹

root = r"C:\Users\Me\Desktop\test"   
for dir, subdirs, files in os.walk(root):   
    if subdirs == [] and files == []:
           send2trash(dir)
           print(dir, ": folder removed")

删除包含此文件的also文件夹

    elif subdirs == [] and len(files) == 1: # if contains no sub folder and only 1 file 
        if files[0]== "desktop.ini" or:  
            send2trash(dir)
            print(dir, ": folder removed")
        else:
            print(dir)

删除只包含.srt或.txt文件的文件夹

    elif subdirs == []: #if dir doesn’t contains subdirectory
        ext = (".srt", ".txt")
        contains_other_ext=0
        for file in files:
            if not file.endswith(ext):  
                contains_other_ext=True
        if contains_other_ext== 0:
                send2trash(dir)
                print(dir, ": dir deleted")

删除小于400kb的文件夹:

def get_tree_size(path):
    """Return total size of files in given path and subdirs."""
    total = 0
    for entry in os.scandir(path):
        if entry.is_dir(follow_symlinks=False):
            total += get_tree_size(entry.path)
        else:
            total += entry.stat(follow_symlinks=False).st_size
    return total


for dir, subdirs, files in os.walk(root):   
    If get_tree_size(dir) < 400000:  # ≈ 400kb
        send2trash(dir)
    print(dir, "dir deleted")
