i have seen people teaching how to use type hints but never felt important before seeing this video. great video!

At minute 14:00, in Python 3.11, we will be able to write Self for the return value rather than "User" which will be handy. Thanks for the video!

Video was maybe a bit longer than it needed to be but much better than the 'just do this' explanation I got elsewhere! I can see how this will make my code more readable to others and importantly to tools, which will be able to parse this information reliably compared to the human-readable docstrings

I need circular module dependency in order to use type hint. How to safely avoid that ? Button class needs Window class and Window class needs Button class. Do I need to use typing.TypeVar() ?

Very nice video. You are huge inspiration man

Emphasize readability, Wonderful! Hope may have some time to talk SOLID design principles and common design patterns in Python in near future.

Are you allowed to have 2 functions with same name in Python? Which one will be called then?

Great video!

It would be great if you made videos on sqlachemy with fastapi. There realy isn't a lot out there on this topic and fastapi is getting more and more popular. I know a lot of the code is very similar to sqlalchemy with flask, but those minor differences do make it confusing.

Thanks, excellent. Do you have a video about annotations?

You have misspelled my name! 😉 It's "Per Persson", not "per person".

LOL at saying stir instead of string for str.
