Missing Language Server Features (autocomplete & inlay hints)

[munro]

There are a lot of things that are working, so this is a really great extension! But I noticed some helpful features are still missing.

Autocomplete on imports

It would be really nice if we could autocomplete imports from mypy!

Autocomplete on objects

This may be relayed to the previous, but also getting autocompletes on objects as well

Inlay hints

Inlay hint support would be really great too 🥲

(notice no inlay hints)

String interpolation shows wrong type

And this was a subtle issue I noticed, it shows the wrong type when hovering over a variable used in string interpolation.

• (variable) foo: int is from PyLance
• and mypy: str is from MyPy.

foo is an int, so it should show int. It appares mypy is showing the coerced type of the variable.

@munro Can you provide the list of extension that you have installed? You should be able to get a list from ~/.vscode/extensions directory or you can run "Open Extensions Folder" command from VS Code.

@munro This is the description of mypy from its website itself:

Mypy is an optional static type checker for Python that aims to combine the benefits of dynamic (or "duck") typing and static typing. Mypy combines the expressive power and convenience of Python with a powerful type system and compile-time type checking. Mypy type checks standard Python programs; run them using any Python VM with basically no runtime overhead.

mypy does just static type checking and is (AFAIK) not suitible as a language server so your feature requests are unsuitable for this extension.

Stay with Pylance for this and use both together!
