In this tutorial, you'll preview the new static typing features in Python 3.12. You'll learn about the new syntax for type variables, making generics simpler to define. You'll also see how @override lets you model inheritance and how you use typed dictionaries to annotate variable keyword arguments.
I’m definitely looking forward to Unpack[…]. This makes kwargs typing manageable for the first time.
The rest is nice too, but no game changers.
