Answer 1

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

(os.listdir()将为您提供目录中的所有内容-文件和目录。)

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

(如果只需要文件，则可以使用os.path将其过滤掉：)

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

or you could use os.walk() which will yield two lists for each directory it visits - splitting into files and dirs for you.

(或者您可以使用os.walk() ，它将为它访问的每个目录生成两个列表-为您拆分为文件和目录。)

If you only want the top directory you can just break the first time it yields

(如果只需要顶层目录，可以在第一次生成目录时中断)

from os import walk

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