Python 2.7 How to list files in a directory AND all sub directories?

Question

I am writing a script that lists number of lanes, words in text files and now I want to add looking for duplicates.

right now I am using this to list all the text files in a directory:

from sys import argv 
script, directory - argv
files = glob.glob(directory + "/*.txt")

If there are any sub-folders in the directory it will not list those files. How can I do it so that it lists all files from all sub-directories as well?

Answer 1

You could use os.walk.

files = [f for (dir, subdirs, fs) in os.walk(directory) for f in fs if f.endswith(".txt")]

Answer 2

You can see Python recursive folder read

and

Use a Glob() to find files recursively in Python?
