Why use them?
Dataclass = a feature that defines classes that contain and encapsulate data.
- Less boilerplate code
- More readability and better code maintainability
- Same lots of coding time (you don’t need to write repr, eq, hash - and make immutable with @property, ne, lt, le, gt, ge)
- Even if you finished all your code, in the future you could change your class, and you need to rewrite the class, but instead we can use dataclasses.
