有没有办法在Python中返回当前目录中所有子目录的列表?

我知道您可以对文件执行此操作,但我需要获得目录列表。


当前回答

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

谢谢你们的建议,伙计们。我遇到了软链接(无限递归)作为dirs返回的问题。Softlinks吗?我们不想要臭软链接!所以…

这只是渲染dirs,而不是软链接:

>>> import os
>>> inf = os.walk('.')
>>> [x[0] for x in inf]
['.', './iamadir']

使用过滤函数os.path.isdir over os.listdir() 类似这样的过滤器(os.path.isdir,[os.path.join(os.path.abspath('PATH'),p) for p in os.listdir('PATH/')])

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)

最简单的方法:

from pathlib import Path
from glob import glob

current_dir = Path.cwd()
all_sub_dir_paths = glob(str(current_dir) + '/*/') # returns list of sub directory paths

all_sub_dir_names = [Path(sub_dir).name for sub_dir in all_sub_dir_paths] 

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))
