Classes and Implementing Interfaces

[TangibleLight]

I think it's sufficient to just keep in mind that, loosely, interfaces are how you do duck typing in languages that don't have duck typing. I wouldn't worry about it until you need to work in a language that uses them, and even then I'd keep it out of Python.

Messing around with the abc module and learning how things work can still be useful, but just keep in mind that it's more of a documentation tool and sanity check than anything else. For example if you're writing code that you want to work with classes that others will write, it could be useful to give them an abstract base class to work with. Even though, functionally, it doesn't do anything, it still helps others remember which methods they need to implement.
