📌 Lecture 24 – Python File Handling | Read Mode ("r")

Welcome to Lecture 24 of our Python Programming Series! 🐍
In this lecture, we dive deep into file handling in Python—specifically focusing on Read Mode ("r").

File handling is one of the most important concepts in Python because almost every real-world project requires working with files—whether it’s reading logs, analyzing text, processing data, or storing user input.
