Python生成目录树代码

用Python实现类似Windows下的tree命令，获取目录树结构。

import os
import os.path

BRANCH = '├─'
LAST_BRANCH = '└─'
TAB = '│  '
EMPTY_TAB = '   '

def get_dir_list(path, placeholder=''):
    folder_list = [folder for folder in os.listdir(path) if os.path.isdir(os.path.join(path, folder))]
    file_list = [file for file in os.listdir(path) if os.path.isfile(os.path.join(path, file))]
    result = ''
    for folder in folder_list[:-1]:
        result += placeholder + BRANCH + folder + '\n'
        result += get_dir_list(os.path.join(path, folder), placeholder + TAB)
    if folder_list:
        result += placeholder + (BRANCH if file_list else LAST_BRANCH) + folder_list[-1] + '\n'
        result += get_dir_list(os.path.join(path, folder_list[-1]), placeholder + (TAB if file_list else EMPTY_TAB))
    for file in file_list[:-1]:
        result += placeholder + BRANCH + file + '\n'
    if file_list:
        result += placeholder + LAST_BRANCH + file_list[-1] + '\n'
    return result

if __name__ == '__main__':
    print(os.path.dirname(os.getcwd()))
    print(get_dir_list(os.path.dirname(os.getcwd())))
