Welcome to our Python Basics series! In this video, “File Not Found Handling with Try Except in Python”, we’ll explore one of the most common errors programmers face — the FileNotFoundError — and how to handle it gracefully using Python’s powerful try-except mechanism.

File operations are a key part of programming. Whether you are reading data, writing logs, or processing user files, there’s always a chance that the file you are trying to access does not exist, is moved, or has been renamed. Without proper error handling, your program will crash and display confusing error messages. In this tutorial, you’ll learn how to prevent that and make your program robust.

📖 Why This Topic Matters

Working with files is an everyday task in Python programming, especially in fields like data science, web development, and automation scripting. However, missing files are inevitable, and how your program reacts determines whether it feels polished or amateurish. By using try-except, you ensure your program:

Doesn’t crash when files are missing

Provides clear guidance to users

Maintains stability in production environments
