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?

As can surmise from my handle, i’m even stricter!
Use Union, not | or Optional where ever possible.
Optional does not allow for future expansion of the typing.
Optional[int]and then want to add float, so have to rewrite itUnion[int, float, None]So write it with Union to begin with.Went thru my | stage like everyone else, but grew out of it.
TypeAlias insists on Union, not |
So Union everywhere ftw
Why? If there is a possibility of making a mistake, Murphy’s law dictates that it’ll occur every damn time. Enough already! KISS principle is in effect.
