I'm trying to create a Protocol for type hinting any azure-native Pulumi Resource that adhere to a Protocol I've been successful in typing: • Instances having

id

,

name

,

location

etc. properties present to get rid of using

Any

with

isinstance()

&

hasattr()

checks • Pulumi Resource Class Objects – which I use to retreive metadata like naming restrictions, public/private DNS information, for a given Resource Class The only problem I haven't been able to overcome is to hint that the type is a subclass or instance of

pulumi.Resource

/

pulumi.CustomResource

Maybe this isn't possible without an Intersection type which isn't yet available in Python? But thought I'd ask here if someone has been able to figure out a workaround or a better alternative way to achieve this?

looking at https://typing.readthedocs.io/en/latest/spec/protocol.html#subtyping-relationships-with-other-types , I think you need to define a separate protocol for pulumi resources

• A protocol is never a subtype of a concrete type.
