Best explanations anywhere, hands down. I wish Kris had an advanced Python (or any other language) series on offer.

Sir please make a video on closures and lexical scoping in python. If like these videos you'll put on your platform with well diagramatic approach that you actually do, this actually makes your content valuable... and makes us visualisation better to excites us to learn more. Lot's of love and hat's off appreciation to your work...
