Exploring the Built-in Debugger for Python's IDLE

IDLE is pretty good at catching mistakes like syntax errors or runtime errors, but there’s a third type of error that you may have already experienced. Logic errors occur when an otherwise valid program doesn’t do what it was intended to do. In this course, you’ll focus on logic errors.

Logic errors cause unexpected behaviors called bugs. Removing bugs is called debugging, and a debugger is a tool that helps you find bugs and understand why they’re happening. In this video, you'll learn how to use IDLE’s Debug Control window.

This is a portion of the complete course, which you can find here:

The rest of the course covers:
- Debugging a Function
- Practicing Setting Breakpoints and Inspecting
- Print Debugging

thanks man your 2 years old video helped me today thanks so much it was so simple and easy no bs

Thanks for the great explainer. I like that the video is slowly explained. I also listened at 1.5x or 2x speed but that is very easy to do, and when i was confused i could easily set it back back at normal speed to work through it. This is much easier than having to slow it down more than 1x when i need to go slower. Thank you!

Thank you very much for the presentation. It is precise and you summarized the presentation after the demo.

Thank you for the content. Just like the other comments, I had to watch it on 4x speed. Very very slow paced.

Thank you very much! Watched the whole video on x2 speed, though
