Welcome to Dr. Sourav Sir’s Classes – your trusted platform for learning Python, Programming, Mathematics, and Data Science in the most practical and exam-oriented way. In today’s lesson, we explore a very important part of Python’s file handling:

👉 How to Perform Read and Write Mode in Python Programming

File handling allows you to store and retrieve data beyond a program’s execution. Understanding how to work with read and write modes is essential for building projects, solving assignments, and preparing for coding interviews.

📌 What You Will Learn in This Video

Introduction to file handling in Python.

Explanation of file modes:

r → Read Mode (default).

w → Write Mode (overwrites existing content).

a → Append Mode.

r+ → Read and Write Mode combined.

Demonstration of how to:

Open a file in write mode and store text.

Open the same file in read mode and retrieve the stored content.

Use r+ to perform both operations together.

Using with open() for safer and cleaner file handling.

Practical examples:

Writing a message to a file.

Reading the message back line by line.

Handling overwriting issues and preventing data loss.

Bonus: Understanding good practices and exception handling in file operations.

By the end of this video, you’ll be able to confidently read from and write to files in Python.

🌟 Why This Topic Matters

File I/O is one of the most frequently used programming skills. Mastering read and write modes will help you in:

Assignments and projects that involve data storage.
