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']

这是简单的递归解

import os
def fn(dir=r"C:\Users\aryan\Downloads\opendatakit"):  # 1.Get file names from directory
    file_list = os.listdir(dir)
    res = []
    # print(file_list)
    for file in file_list:
        if os.path.isfile(os.path.join(dir, file)):
                res.append(file)
        else:
            result = fn(os.path.join(dir, file))
            if result:
                res.extend(fn(os.path.join(dir, file)))
    return res


res = fn()
print(res)
print(len(res))

使用python-os-walk实现。(http://www.pythonforbeginners.com/code-snippets-source-code/python-os-walk/)

import os

print("root prints out directories only from what you specified")
print("dirs prints out sub-directories from root")
print("files prints out all files from root and directories")
print("*" * 20)

for root, dirs, files in os.walk("/var/log"):
    print(root)
    print(dirs)
    print(files)

使用OS walk

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

如果您需要一个递归的解决方案来查找子目录中的所有子目录，请使用前面建议的walk。

如果您只需要当前目录的子目录，请将os. xml目录合并在一起。使用os.path.isdir

下面这个类将能够获得一个给定目录中的文件，文件夹和所有子文件夹的列表

import os
import json

class GetDirectoryList():
    def __init__(self, path):
        self.main_path = path
        self.absolute_path = []
        self.relative_path = []


    def get_files_and_folders(self, resp, path):
        all = os.listdir(path)
        resp["files"] = []
        for file_folder in all:
            if file_folder != "." and file_folder != "..":
                if os.path.isdir(path + "/" + file_folder):
                    resp[file_folder] = {}
                    self.get_files_and_folders(resp=resp[file_folder], path= path + "/" + file_folder)
                else:
                    resp["files"].append(file_folder)
                    self.absolute_path.append(path.replace(self.main_path + "/", "") + "/" + file_folder)
                    self.relative_path.append(path + "/" + file_folder)
        return resp, self.relative_path, self.absolute_path

    @property
    def get_all_files_folder(self):
        self.resp = {self.main_path: {}}
        all = self.get_files_and_folders(self.resp[self.main_path], self.main_path)
        return all

if __name__ == '__main__':
    mylib = GetDirectoryList(path="sample_folder")
    file_list = mylib.get_all_files_folder
    print (json.dumps(file_list))

而样本目录看起来像

sample_folder/
    lib_a/
        lib_c/
            lib_e/
                __init__.py
                a.txt
            __init__.py
            b.txt
            c.txt
        lib_d/
            __init__.py
        __init__.py
        d.txt
    lib_b/
        __init__.py
        e.txt
    __init__.py

结果

    "files": [
      "__init__.py"
    ],
    "lib_b": {
      "files": [
