使用OS walk

sub_folders = []
for dir, sub_dirs, files in os.walk(test_folder):
    sub_folders.extend(sub_dirs)

这将列出文件树的所有子目录。

import pathlib


def list_dir(dir):
    path = pathlib.Path(dir)
    dir = []
    try:
        for item in path.iterdir():
            if item.is_dir():
                dir.append(item)
                dir = dir + list_dir(item)
        return dir
    except FileNotFoundError:
        print('Invalid directory')

Pathlib是3.4版的新功能

import os

d = '.'
[os.path.join(d, o) for o in os.listdir(d) 
                    if os.path.isdir(os.path.join(d,o))]

这个函数，对于给定的父目录，递归地遍历它的所有目录，并打印它在其中找到的所有文件名。也有用。

import os

def printDirectoryFiles(directory):
   for filename in os.listdir(directory):  
        full_path=os.path.join(directory, filename)
        if not os.path.isdir(full_path): 
            print( full_path + "\n")


def checkFolders(directory):

    dir_list = next(os.walk(directory))[1]

    #print(dir_list)

    for dir in dir_list:           
        print(dir)
        checkFolders(directory +"/"+ dir) 

    printDirectoryFiles(directory)       

main_dir="C:/Users/S0082448/Desktop/carpeta1"

checkFolders(main_dir)


input("Press enter to exit ;")

在ipython中复制粘贴友好:

import os
d='.'
folders = list(filter(lambda x: os.path.isdir(os.path.join(d, x)), os.listdir(d)))

从打印(文件夹)输出:

['folderA', 'folderB']

这个答案似乎并不存在。

directories = [ x for x in os.listdir('.') if os.path.isdir(x) ]
