Webinar Description

Python Webinar III is designed to help Python developers move from “working code” to reliable, production-ready programs. In this hands-on webinar, participants learn how to identify, diagnose, and handle errors effectively while building Python applications that can deal with unexpected situations.

Rather than avoiding errors, this session teaches how to understand and use errors as learning tools. Participants work through real debugging scenarios, practice handling failures gracefully, and learn how professional Python developers approach troubleshooting and reliability.

All exercises and labs are completed using Visual Studio Code, reinforcing practical debugging workflows and best practices used in real development environments.

Lab & Exercise Structure

Each lab is:

  • Based on realistic failure scenarios

  • Instructor-guided with live explanation

  • Designed to build debugging confidence

  • Executed entirely in Visual Studio Code

Labs emphasize thinking through problems rather than memorizing fixes.
