Any code editor support for Python 3.12 new type syntax yet (PEP 695)?

Been 2 months since the update but I don’t see any news about code editor support for the new syntax.

This kind of makes sense, i don’t expect code editor support to pop up so fast, but i was at least hoping to hear some news about it.

The PEP in question: PEP 695

I’m not experienced with it, but it looks like Ruff has support?

Good news, On VSCode, with Pylance and Ruff I have both intellisense and new syntax support.

Meh news, symtax highlighting is fucky for generic functions’ return type.

Example:

def add[T](a: T, b: T) -> T:
    return a + b

On my setup the -> is colored red but is supposed to be white, that also happens with only the Python extension, so I’m guessing it will be fixed soon.

Besides that, I’m actually surprised this was hidden under my nose as Ruff was already installed, but Pylint and MyPy both started reporting errors which gave the impression that none of my installed extensions support the new syntax. kind of a rookie mistake on my part not to check every extension’s website for updates.

Anyway, thanks for the answer, I’m glad to finally be able to utilize this.

Heard that only pyright, not mypy, has support for the new typing syntax

Wouldn’t hurt to try out another static type checker. And if pyright is better. Switch.

Using mypy btw. Haven’t moved on to support the new typing syntax

I haven’t checked because Python 3.12 breaks Pytest for us (OOM), so we’re sticking with 3.11 for now.
