Context Managers and Cross Cutting concerns in Python | NucuLabs

| | Hello, In this short article I would like to talk about context managers. I personally consider that at the core they are just a form of decorators. If you don't know what a decorator is check the Decorator Pattern Wikipedia article. Decorators can be used to implement cross-cutting concerns. We have componentA and we need logging and security, we could write the logic for logging and security handling in componentA but some people consider component a should be componentA not componentAthatAlsoKnowsAboutSecurityAndOtherStuff. Since it's not the component's responsibility to authorize requests or log calls to a external logging service, we can wrap the componentA into a decorator that does just that.
