Article Summary
The `os` module in Python is a built-in library that lets your code interact with the operating system — managing files, directories, environment variables, and paths across Windows, Mac, and Linux. This article covers key methods like `os.getcwd()`, `os.mkdir()`, `os.listdir()`, and `os.walk()`. You'll gain a clear, practical understanding of what the `os` module does and when to use it.
The Python os module is a Swiss army knife for your operating system, giving you access to files, directories, and other operating system features in your Python code. This module acts as a bridge between your code and the proprietary way your os handles its file system. It’s also a portable module, meaning you can use the same methods and get the same results whether you’re running your Python code on Windows, Mac OSX, or Linux so long as the os supports the functionality. If the operating system doesn’t support a method, an OSerror is raised.
This module has a lot of functionality. You can use it to get the path of your current directory, get the names of files and folders in that directory, change directories, delete a directory, and much more. The best way to learn what you can do with this module is through examples of real Python code, such as in the list of examples below. So open your Python IDE and try out some of these examples on your own.
Python os module methods with examples
Get the name of the operating system module imported using os.name
While you might think this attribute would tell you the name of the operating system your python code is running on, that’s not the case. Instead, it returns a string that is the name of the Python module used by the os module.
For example:
| # Import the os module import os # Print the name print(os.name) # Will print “posix” on Mac and Linux and “nt” on Windows |
