Chapter Overview
This chapter introduces file handling in Python, essential for storing and processing data persistently. Students learn about types of files—text and binary, opening and closing files, reading/writing data using file methods, file modes, and using context managers. It empowers learners to develop programs that can handle data beyond runtime.
