Error Handling and Debugging

Programs do not always work perfectly the first time.

Sometimes code crashes. Sometimes it runs but gives the wrong result.

Good developers know how to handle errors and fix bugs.

This module teaches you how to write safer programs and debug problems with confidence.

What You Will Learn

  • How try and except work
  • How to handle multiple exceptions
  • How to use finally
  • How to create errors with raise
  • How assertions work
  • How to use logging
  • How to debug in VS Code
  • Common Python errors and how to fix them
  • How to build safer programs

Why This Module Matters

Real programs must handle unexpected problems.

Users may type bad input. Files may be missing. Data may be wrong.

Without debugging skills, it is hard to fix issues.

With these skills, you can find problems faster and build reliable software.

Practical Focus

You will build beginner-friendly examples such as:

  • Safe calculators
  • Input validators
  • Bug fixing exercises
  • Error logs
  • Debug practice apps

Success Goal

By the end of this module, you will understand common Python errors, debug code step by step, and handle problems like a real developer.
