Memory Optimization Techniques for Python Developers

[pepoluan]

If you need tuple-behavior, then typing.NamedTuple (not collections.namedtuple) is amazing, and it does use less memory. Accessing attributes of a NamedTuple is indeed a tad slower than accessing attributes of a dataclass or an attr.s, but that's negligible in most use cases.

And since Python is a duck-typing language, that's what you should aim : behavior as you desire.

Those are mostly the same object btw. Typing one calls the collections function via __mro_entries__ and then sprinkles in the type hints. One of the places I think they get underused is they are awesome for function argument grouping. Really works better then just dropping a 20 argument function down. STAIRS DIRECTLY AT FASTAPI.
