Python 3.4在标准库中引入了pathlib模块，它提供了一种面向对象的方法来处理文件系统路径:

from pathlib import Path

p = Path('./')

# All subdirectories in the current directory, not recursive.
[f for f in p.iterdir() if f.is_dir()]

要递归地列出所有子目录，路径通配符可以与**模式一起使用。

# This will also include the current directory '.'
list(p.glob('**'))

请注意，一个*作为glob模式将非递归地包括文件和目录。为了只获取目录，可以在后面追加一个/，但这只在直接使用glob库时有效，而不是通过pathlib使用glob时:

import glob

# These three lines return both files and directories
list(p.glob('*'))
list(p.glob('*/'))
glob.glob('*')

# Whereas this returns only directories
glob.glob('*/')

因此Path('./').glob('**')匹配与glob相同的路径。一团(“* * /”,递归= True)。

Pathlib也可以通过PyPi上的pathlib2模块在Python 2.7中使用。

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 ;")

import os
path = "test/"
files = [x[0] + "/" + y for x in os.walk(path) if len(x[-1]) > 0 for y in x[-1]]

import os

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

函数返回给定文件路径内所有子目录的List。将搜索整个文件树。

import os

def get_sub_directory_paths(start_directory, sub_directories):
    """
    This method iterates through all subdirectory paths of a given 
    directory to collect all directory paths.

    :param start_directory: The starting directory path.
    :param sub_directories: A List that all subdirectory paths will be 
        stored to.
    :return: A List of all sub-directory paths.
    """

    for item in os.listdir(start_directory):
        full_path = os.path.join(start_directory, item)

        if os.path.isdir(full_path):
            sub_directories.append(full_path)

            # Recursive call to search through all subdirectories.
            get_sub_directory_paths(full_path, sub_directories)

return sub_directories

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
