This can have a lot of applications, and keeping descriptors in mind might come in handy when facing a hard problem. The goal of the talk is to explore descriptors, and how they can be written, as well as analysing some interesting examples in well-known libraries or projects in order to identify scenarios where descriptors are the Pythonic way to go
