In this short chapter, we looked at different techniques and suggestions for debugging and troubleshooting our code. Debugging is an activity that is always part of a software developer's work, so it's important to be good at it.

If approached with the correct attitude, it can be fun and rewarding.

We explored techniques to inspect our code base on functions, logging, debuggers, traceback information, profiling, and assertions. We saw simple examples of most of them and we also talked about a set of guidelines that will help when it comes to facing the fire.

Just remember always to stay calm and focused, and debugging will be much easier. This too, is a skill that needs to be learned and it's the most important. An agitated and stressed mind cannot work properly, logically, and creatively, therefore, if you don't strengthen it, it will be hard for you to put all of your knowledge to good use.

In the next chapter, we are going to explore GUIs and scripts, taking an interesting detour from the more common web-application scenario.
