Watch out for this common generator pitfall.

What happens to a try/finally, with block, or async with block inside a generator if the generator isn't exhausted? Does the cleanup code still run? When and how does it run? In this video we take a look at the answers to these questions and learn how to avoid a common situation where cleanup code doesn't run when you want it to.
