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")

如果你确定你想要删除整个目录树，并且不再对目录的内容感兴趣，那么爬行整个目录树是愚蠢的…只需从python中调用本机操作系统命令即可。它将更快，更有效，更少的内存消耗。

RMDIR c:\blah /s /q 

例如*那晚尼克斯。

rm -rf /home/whatever 

在python中，代码看起来像..

import sys
import os

mswindows = (sys.platform == "win32")

def getstatusoutput(cmd):
    """Return (status, output) of executing cmd in a shell."""
    if not mswindows:
        return commands.getstatusoutput(cmd)
    pipe = os.popen(cmd + ' 2>&1', 'r')
    text = pipe.read()
    sts = pipe.close()
    if sts is None: sts = 0
    if text[-1:] == '\n': text = text[:-1]
    return sts, text


def deleteDir(path):
    """deletes the path entirely"""
    if mswindows: 
        cmd = "RMDIR "+ path +" /s /q"
    else:
        cmd = "rm -rf "+path
    result = getstatusoutput(cmd)
    if(result[0]!=0):
        raise RuntimeError(result[1])

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)

对于Windows，如果目录不是空的，并且你有只读文件或者你会得到这样的错误

访问被拒绝 该进程无法访问该文件，因为它正被另一个进程使用

试试这个，os。system('rmdir /S /Q "{}"'.format(directory))

它相当于Linux/Mac中的rm -rf。

基于递归的纯pathlib解决方案:

from pathlib import Path

def remove_path(path: Path):
    if path.is_file() or path.is_symlink():
        path.unlink()
        return
    for p in path.iterdir():
        remove_path(p)
    path.rmdir()

支持Windows和符号链接

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))
