If using python with type annotations, linters like ruff and mypy do a great job at identifying issues. It's no substitute for tests and nor will it give you the same guarantees that rust will at compile time. But I think it improves the base quality of the code.

The thing I find annoying with MyPt is trying to tell it I'm doing variable shadowing.

E.g. X is a list of strings Translate X to a list of indices Translate X back to a list of strings.

In that paragraph the input and output types are the same, but not complains about the second line.

I always have to introduce a variable with a new name.

Yeah I see what you mean, you can always disable specific features, but I think that's a habit mypy tries to enforce. They consider redefining a variable bad practice.

Even in rust you have to be explicit about doing the same thing with an extra "let" statement.

		Yeah that's fair enough, and I've lived with it because of how good MyPy is. But I always end with weird variable names like uuids_as_list as a result!
