What type checker do you recommend?
It's day and night compared to typeguard.
Also the dev is... Completely out of this world
Someone using Python doesn't "just use Rust", there are very clear pros and cons and people already using Python are doing so for a reason. It is sometimes helpful to have type checks in Python though.
> Use beartype to assure the quality of Python code beyond what tests alone can assure. If you have yet to test, do that first with a pytest-based test suite, tox configuration, and continuous integration (CI). If you have any time, money, or motivation left, annotate callables and classes with PEP-compliant type hints and decorate those callables and classes with the @beartype.beartype decorator.
Don't get me wrong, I think static type checking is great. Now if you need to add a decorator on top of each class and function AND maintain 100% code coverage, well that does not sound like "zero-cost" to me. I can hardly think of a greater cost just to continue dynamically typing your code and maintain guarantees about external dependencies with no type hints.
And anyway beartype has a mechanism to run a hook once and it will automagically decorate all functions.
Pylance with pyright[0] while developing (with strict mode) and mypy[1] with pre-commit and CI.
Previously, I had to rely on pyright in pre-commit and CI for a while because mypy didn’t support PEP 695 until its 1.11 release in July.
Do you happen to have discrepancies between both? (e.g. an error raised by one and not the other)
