Posted on  by 



Walk ('/', printfnmatches, '.mp3') The old os.path.walk function was a challenge for many to use because of the need to pass a function into the walk,. OS module in Python provides various methods for interacting with the operating system. It comes under Python’s standard utility module, so there is no need to install it externally. Os.path is a submodule of OS module which contains some useful functions on pathnames. The path parameters are either strings or bytes. Os.path.walk is a deprecated function. You really should use os.walk, which has no need for either a callback function or helper arguments (like a in your example). For directory, dirnames, filenames in os.walk(somepath): # run here your code.

In this article we will discuss different methods to generate a list of all files in directory tree.

Creating a list of files in directory and sub directories using os.listdir()

Os.path.walk

Python’s os module provides a function to get the list of files or folder in a directory i.e.
It returns a list of all the files and sub directories in the given path.

We need to call this recursively for sub directories to create a complete list of files in given directory tree i.e.
Call the above function to create a list of files in a directory tree i.e.

Creating a list of files in directory and sub directories using os.walk()

Python’s os module provides a function to iterate over a directory tree i.e.
It iterates of the directory tree at give path and for each directory or sub directory it returns a tuple containing,
(<Dir Name> , <List of Sub Dirs> , <List of Files>.
Iterate over the directory tree and generate a list of all the files at given path,
Complete example is as follows,
