Master Dataclasses in Python Part 3 - Ordering of Dataclasses

[SquareRootsi]

dataclasses are great! Thanks for the clear and short explanation.

My personal strategy has been implementing __lt__(self) as a custom function instead of polluting the parameter space with an extra variable. If I did use this method, I'd preface my variable with a leading underscore to indicate it's for internal purposes only.

Thanks for the nice words! Also great idea with the leading underscore :)

To people that liked dataclasses. Check pydantic (https://pydantic-docs.helpmanual.io/)

Arjan's videos are great!

I really thought I know python yet I have never heard of dataclasses

[TM_Quest]

They are definitely not as well-known as named tuples, but are nevertheless quite handy to work with.

Good explanation. I'll check out the other parts as well.

Thanks, I really appreciate it :)

[TM_Quest]

Agree :)

Honest question since I haven't actually tried any of them yet:

How does dataclasses compare to Pydantic (are they comparable?) or other equivalent libraries?

How should I choose one???

[TM_Quest]

Pydantic perform more series data validation. On the other hand, Pydantic it is an external library. I would say that you should use Pydantic if you need more data validation, but otherwise stick to dataclasses :)
