Re:Statically-typed error handling in Python using Mypy by avremel on Sunday December 08, 2019 @07:22PM (#21739494)
I was referring to defining optional keys.

If you have a dict with some keys which are optional, you need to create a separate subclass (with `total=False`) just for those optional keys.

With TypeScript, I can just use `key?: type`.
