![]() ![]() ![]() Searching for Files Recursively in Python By changing "*" to "*.py", we could focus on just the Python files, or specify a full filename, etc. You c n see we list two python files and the subdirectory. I’ve tried to keep this folder pretty minimal. Listing the contents of the directory I was working in, I get the following output: We can then call the glob method on the path object to list all the files in this directory using “*.” The glob expression, *, will expand to mean “all files and directories,” just as it would if we used “ls *” on Linux or “dir *” on Windows. We pass in a “.” as a starting point to construct the Path. This will list the contents of the current working directory, that is, wherever we run it from (not where the Python script is located). To start getting our hands on the Pathlib module, we can run the following code either as a file or from the command prompt. Using the Path class, the root of the concrete classes in Python, allows the code we’ll demonstrate in this article to work in both environments. Advertisementsįor example, passing a file or directory name to the Path class constructor creates a concrete object of the type PosixPath on Linux or Unix-style systems (like macOS) or a WindowsPath object on Windows. Although this module has a concept of “pure” paths (i.e., paths you can manipulate without really referring to the file system), it’s much more common that we simply want to construct a concrete path class. Pyth n’s pathlib module provides most of what we need for this task. Whether we’re dealing with the user’s home directory, the current working directory, or the directory containing an executing Python file, we’ll always need a way to build and manipulate paths robustly. ![]() The PathLib Module: Defining the Path Structure For example, how would you find a file in a subdirectory of the user’s home directory, what’s the path of the currently executing file, or given a Python module name, where did that name come from? With the tools we’ll provide in this article, you’ll be able to locate any file in your system with ease. We’ll also learn how to find various paths we might need to use as a starting point. ![]() This guide will focus on the pathlib module and teach you the basics of finding files and manipulating paths, including using glob patterns and recursive searching. Python 3.4 introduced the pathlib module as an object-oriented API for filesystem paths. Before version 3.4, one would have used the glob module to find a file and used os.path module to perform other path operations, such as getting a directory given an absolute filename or creating an absolute path from a relative path. However, finding files in Python can be daunting if you don’t know where to start, especially since you can choose between more than one library to find and manipulate paths and files. Naturally, therefore, Python has support for the kinds of file searching and path operations one can do in a bash script, for example. In addition to being an excellent general-purpose programming language, Python is also well known as a handy language for scripting.

This Python program uses functions provided by the os module recursively navigate through a directory tree while listing the directories, subdirectories and files. ![]()
