Excellent - beautifully explained with an example rather than jumping straight into the 5 levels of logging as most videos do

[floatpoint]

Well there goes one of my bad habits. Don't know if I skipped over the section, but none of the python tutorials I watched spoke about logging, even in the debug sections. Thank you for enlightening me

EXCELLENT VIDEO!!!

Thanks so much for this video! I was struggling with my first program to use logging.

I kept using the default (root) logging...your video showed me to built my own logger.

I needed to change the fileHandler on the fly, this wasn't covered in the video, but I was able to figure out how to remove the previous fileHandler and add a new one with the new (different) file.


I wasted way too much time (days) reading stackoverflow for answers...After a couple of hours looking for a video tutorial, I stumbled across your video.

THANKS TONS!

How can I copy the generated log to different directory ? By default the logs are generated in same directory from were the script is run.
