Front End Web Development Techdegree Graduate 30,654 PointsSo what is the outcome of this section?
Should we use PDB every time before we execute the code and then get rid of it? Should we always log everything into a log.file?
Can anyone more experienced in practice tell me if there is like a Zen practice / Mantra that we should follow regarding the logging/debugging concept in here.

If you're curious about intermediate states during execution or if there is unexpected behavior, then pdb and logging become very useful instead of adding print statements then deleting those. So the outcome of this section is to be exposed to tools to help you get to success. Though I still use print statement now and then.
Personally, I don't use pdb very often mainly because I can usually find my mistakes through tests, printing, and inspection. I find pdb very useful when inspecting unfamiliar code. I usually save logging for mature projects when I would like to track code behavior for future debug or general data collection.
