遍历d盘下的所有文件

from os import listdir
from os.path import isfile ,join,isdir



def one_dir_file(path):   #打印该目录下所有文件，跳过目录下的子文件夹
    print('path:',path)
    for item in listdir(path):
        if isfile(join(path,item)):
            print(item)
    print('\n')

def all_dir_file(path):
    one_dir_file(path)
    content = ''
    for item in listdir(path):     #对子文件夹进行递归遍历
        if  isdir(join(path,item)):
            content = content+all_dir_file(join(path,item))
            continue
        content = content+item
        content = content+'\n'
    return content



print(all_dir_file('D:'))
