Exercise 22: Using the OS Module in Python

In this exercise, we will explore how to use the OS module in Python to interact with the operating system. The OS module provides a way to perform various operations on files and directories, such as creating, deleting, renaming, and listing them.

Getting Started

Before we begin, make sure you have Python installed on your computer. You can download Python from the official website at https://www.python.org/.

Importing the OS Module

To use the OS module in Python, we need to import it first. Here’s how you can do that:

import os

Working with Directories

Let’s start by creating a new directory using the OS module:

os.mkdir('new_directory')

This code will create a new directory called ‘new_directory’ in the current working directory.

We can also check if a directory exists before creating it:

if not os.path.exists('new_directory'):
    os.mkdir('new_directory')

This code will only create the ‘new_directory’ if it does not already exist.

Listing Files in a Directory

We can use the os.listdir() function to list all the files and directories in a given directory:

files = os.listdir('.')
for file in files:
    print(file)

This code will list all the files and directories in the current working directory.

Renaming and Deleting Files

To rename a file, we can use the os.rename() function:

os.rename('old_file.txt', 'new_file.txt')

This code will rename the file ‘old_file.txt’ to ‘new_file.txt’.

Similarly, to delete a file, we can use the os.remove() function:

os.remove('file_to_delete.txt')

This code will delete the file ‘file_to_delete.txt’.

Conclusion

That’s it! You have learned how to use the OS module in Python to perform various operations on files and directories. Experiment with the code examples provided and try implementing more functionalities on your own.

For more information on the OS module, you can refer to the Python documentation: https://docs.python.org/3/library/os.html.
