问题描述

如何在 Python 中列出目录的所有文件并将它们添加到 list 中?

How can I list all files of a directory in Python and add them to a list?

推荐答案

os.listdir() 将获取目录中的所有内容 - 文件 和 >目录.

os.listdir() will get you everything that's in a directory - files and directories.

如果你想要只文件，你可以使用 os.path:

If you want just files, you could either filter this down using os.path:

from os import listdir
from os.path import isfile, join
onlyfiles = [f for f in listdir(mypath) if isfile(join(mypath, f))]

或者你可以使用 os.walk() 它将为它访问的每个目录生成两个列表 - 分成文件和dirs 给你.如果你只想要顶级目录，你可以在第一次产生时中断

or you could use os.walk() which will yield two lists for each directory it visits - splitting into files and dirs for you. If you only want the top directory you can break the first time it yields

from os import walk

f = []
for (dirpath, dirnames, filenames) in walk(mypath):
    f.extend(filenames)
    break

或者更短:

from os import walk

filenames = next(walk(mypath), (None, None, []))[2]  # [] if no file
