Robust Error Handling and File I/O

This unit focuses on building resilient Python programs through exception handling, safe resource management, and data serialization. Students will learn to catch, raise, and structure exceptions, perform text and binary file operations, and organize persistent data using JSON to prepare for larger, data-driven projects.

Learning Objectives

• Analyze exception types, tracebacks, and error propagation to identify root causes and point of failure in Python programs
• Apply try, except, else, and finally constructs and raise custom exceptions to prevent crashes and maintain predictable program flow
• Demonstrate safe file I/O by opening, reading, writing, iterating, and closing text and binary files, including copying binary data and using context managers
• Evaluate and implement JSON serialization and deserialization techniques to organize, persist, and load structured program data
