That tidbit about "variables with default values must come after the ones without them", just explained a big problem I was having. Thank you!

[@FrocketGaming]

Thanks for this. As I was watching and working on a selenium web scraping script I realized I could make a config dataclass to store all the css_selectors / xpaths I need for this script!

[@davidl3383]

Thank you. Very clear like your udemy couse ;)

[@adhd_arti]

Great video as always! Have you by any chance made a video about Pydantic (couldn't find it), or are you maybe planning to?

[@velicihanates3288]

You could have used two asterix operators to insert json in your person class
'bob = Person(**json)'

[@Indently]

Only if your dataclass fits PERFECTLY the data from the JSON, otherwise it will throw an error.

[@velicihanates3288]

@@Indently thanks for telling, I really enjoy your python tutorials!

[@thepackbot]

that's called unpacking.

[@user-of9dq5dl2x]

your explaination is very helpful for understanding the question 'why we need to do that ', and i like your explaination for reading a json file to an object. Thank you very much for this good video.

Nice! Named tuple vs dataclass for the next video?

[@Indently]

Possibly someday!

[@NoidoDev]

Is it better to use that for data or some dict? For example, It seem that I won't be able to get "keywords".
Also, there's a difference between __slots__ and slots=True, which is that you can use default value with the new method.

Do u have a course… or mentoring program

[@Indently]

I have a couple of courses at: indently.io

[@lostsoul8634]

I'm learning python... bob= Person(**json) is better?

[@jeyosman1]

I just wanted to take a moment to express my sincere appreciation for your exceptional explanations and the engaging speed at which you communicate. Your clarity and enthusiasm truly stand out, making learning from you an absolute pleasure. Thank you for your dedication and talent-I genuinely admire the way you convey information

[@DrDeuteron]

Don't forget the dataclasses.Field object...can be very useful when dealing with telemetry.
There's also the "astuple" method that is attached to the class.

Why are you teaching people how to use me?

Because you're great and deserve to be treated with respect.
