Error Handling and File I/O

This unit teaches students how to make Python programs more robust by handling errors and working with files and serialized data. Students will learn exception design and handling patterns, safe file operations for text and binary data, and how to organize and persist data using JSON.

Learning Objectives

• Analyze Python exceptions and tracebacks to identify root causes and determine appropriate handling strategies
• Apply try, except, else, and finally constructs and raise exceptions intentionally to prevent crashes and enforce program correctness
• Demonstrate file I/O techniques by opening, reading, writing, looping through text files, and copying binary files safely
• Evaluate and implement JSON serialization and deserialization to organize, persist, and load structured application data
