For example:

class FooBar:
    def __init__(self):
        self.a: int = None
        self.foo: str = None

Is this bad practice/go against PEP guidelines or is it fine?

    LOL have never used the match statement. Has been one of those features just outta reach. So close can taste it. But alas …

    Now py310 is here. Still not enthusiastic about it. But over time maybe will come around.

    __slots__ = (...) or frozen. Same thing. Make the data class read-only reducing memory usage by 30-40%. Like the memory usage difference between tuple and list.

    From experience, in stubs, __slots__ need to include "__weakref__". If frozen, then don’t include "__weakref__".

    How about this. Lets meet each other half way.

    I’ll stop thinking of the match statement as thorium reactor toxic waste.

    And maybe you can take a read through of the frozen option for dataclasses.

    Sound fair?

      If I need something like slots I’ll keep them in mind. Thanks for calling my attention to them.
