Handling Exceptions in Python

Runtime errors do not always have to bring a program to a stop. This Block introduces try and except as a clear way to handle predictable failures, give useful feedback, and let the rest of the program continue when recovery makes sense.

What you will learn:

• Wrap risky operations in focused try blocks
• Understand how execution moves to a matching except handler
• Handle invalid number conversions with ValueError
• Handle missing dictionary keys with KeyError
• Handle missing files with FileNotFoundError
• Use multiple specific handlers while keeping unexpected problems visible

By the end, you will be able to turn predictable runtime failures into calm, helpful program behavior without hiding real bugs behind a broad except block.
