[ Python 常見問題 ] How to list all files of a directory?

Source From Here 
Question 
How can I list all files of a directory in python and add them to a list? 

How-To 
os.listdir() will get you everything that's in a directory - files and directories. 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(".") if isfile(join(".", f))] // Collect only file not directory
>>> for f in onlyfiles: print("%s" % (f)) // Print out the collection

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 just break the first time it yields:

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