In this video, you’ll learn how to handle file input and output (I/O) operations in Python. We’ll cover how to open, read, and write files using Python’s built-in open() function. You’ll also learn about different file modes (reading, writing, appending, etc.) and how to handle exceptions that might occur during file operations. By the end of the video, you’ll understand how to manipulate text files, append data, and implement error handling using try-except blocks to make your file handling operations more robust.
