Python’s with statement is powered by a language feature called context managers. It helps you simplify some common resource management patterns by abstracting their functionality and allowing them to be factored out and reused.

In this course you’ll learn how context managers and the with statement work in Python, including the difference between class-based and function-based context managers, as well as some other tricks that will make you a more efficient Python developer.

Nice explanation of Context Managers..:)

Detailing the various approaches in context really helps to understand the concept and how one might arrive at an implementation with respect to their own, or a community’s coding knowledge. The possible trouble of using an obscure approach since having its roots revealed is avoided by the awareness of what’s going on and how those who don’t know might get lost in an implementation that’s too far removed syntactically from the underlying logic. Without these videos even saying that would be impossible. Thanks for yet another insight.
