I don't usually comment on a video unless it really moved me. This tutorial was perfect. Upgrade pip -> Git repo -> virtual environment -> Flask configuration -> Debugging demo (stepping/variable watching/call stack monitoring). It's beautiful. Just a small boo-boo on the comment 'the hello is being called by sum function'. I'm sure you meant to say hello is calling sum.
