Beginner Level Python Programming Training – File Handling

Welcome to Part 20 of the Beginner Level Python Programming Training series! In this session, we explore file handling in Python—a fundamental skill that allows you to read from, write to, and manage files directly through your code.

Whether you’re working with text logs, data files, or user-generated content, file handling is essential for building real-world applications.

✅ What You’ll Learn in This Video:
✔️ Opening and reading files using the open() function
✔️ Writing to and appending content in files
✔️ Using read(), readline(), and readlines() effectively
✔️ Understanding file modes like 'r', 'w', 'a', and 'x'
✔️ Best practices: closing files and using with statement for file safety

💡 Why This Step Matters:
🔹 Teaches how to work with data outside of your program
🔹 Enables saving, logging, and retrieving information
🔹 Builds a foundation for working with CSVs, JSON, and databases later
🔹 Reinforces good practices for managing system resources
