In neovim ,how to do refactoring python code?
Hi, maintainer of rope here. There are a number of different options to use rope in Vim/Neovim, we've documented them in this page https://github.com/python-rope/rope/wiki/Rope-in-Vim-or-Neovim
-
Open Source Python libraries/projects that need contributions?
If you're looking for something with a bigger codebase, then the rope library in which pylsp-rope is based on is also welcoming of contributions.
-
Completion and auto imports
I think rope is the standard for refactoring, and should provide autoimports soon, though pyright might also be good for that.

What motivates you writing open source software?
However, my biggest and most popular open source project is one that I don't originally write, but rather I inherited a popular project that has been abandoned by their original author/maintainers. I use Python a lot, so I wanted to contribute to the community in a significant way, so unlike my other projects I do take the time promoting this project as well. I felt it's more like a community service for this project.

What are some interesting open source projects to contribute code to?
I am the maintainer rope and pylsp-rope. They are libraries for automated Python refactoring and to do that from any LSP-capable editors. We are always welcoming contributors of all levels.

Why IDEs are Important
Rope has first class support for Vim and it can do a move refactoring, among other refactorings. From this, this feature is available from python-mode and ropevim.

Why did you switch from another language to Rust? Do you regret not learning it earlier?
Okay this depends: if your code is static: perfectly possible for example with https://github.com/python-rope/rope (used for example by VS Code). If it's dynamic / generated via metaprogramming: I never tried it but I can't imagine that it'd work there, yes. However java tooling also can't do that because it simply doesn't support metaprogramming in any noteworthy way.

Returning to snake's nest after a long journey, any major advances in python for science ?
As other folks have commented, type hints are now a big deal. For static typing the best checker is pyright. For runtime checking there is typeguard and beartype. These can be integrated with array libraries through jaxtyping. (Which also works for PyTorch/numpy/etc., despite the name.)

Boring Python: Code Quality
I got good use of the run-time type checking of typeguard [0] when I recently invoked it via its pytest plugin [2]. For all code visited in the test suite, you get a failing test whenever an actual type differs from an annotated type.

Im listening...
But you can use a library like typeguard to get runtime typechecking. Or run mypy over the code to get static typechecking.

Python’s “Type Hints” are a bit of a disappointment to me
Every point in this blog post strikes me as either (1) unaware of the tooling around python typing other than mypy, or (2) a criticism of static-typing-bolted-on-to-a-dynamically-typed-language, rather than Python's hints. Regarding (1), my advise to OP is to try out Pyright, Pydantic, and Typeguard. Pyright, especailly, is amazing and makes the process of working with type hints 2 or 3 times smoother IMO. And, I don't think points that fall under (2) are fair criticisms of type *hints*. They are called hints for a reason.
Otherwise, here's a point-by-point response, either recommending OP checks out tooling, or showing that the point being made is not specific to Python.
> type hints are not binding.
There are projects [0][1] that allow you to enforce type hints at runtime if you so choose.
It's worth mentioning that this is very analogous to how Typescript does it, in that type info is erased completely at runtime.
> Type checking is your job after all, ...[and that] requires maintenance.
There are LSPs like Pyright[2] (pyright specifically is the absolute best, IMO) that report type errors as you code. Again, this is very very similar to typescript.
> There is an Any type and it renders everything useless
I have never seen a static-typing tool that was bolted on to a dynamically typed language, without an `Any` type, including typescript.
> Duck type compatibility of int and float
The author admits that they cannot state why this behavior is problematic, except for saying that it's "ambiguous".
> Most projects need third-party type hints
Again, this is a criticism of all cases where static types are bolted on dynamically typed languages, not Python's implementation specifically.
> Sadly, dataclasses ignore type hints as well
Pydantic[3] is an amazing data parsing library that takes advantage of type hints, and it's interface is a superset of that of dataclasses. What's more, it underpins FastAPI[4], an amazing API-backend framework (with 44K Github stars).
> Type inference and lazy programmers
The argument of this section boils down to using `Any` as a generic argument not being an error by default. This is configurable to be an error both in Pyright[5], and mypy[6].
> Exceptions are not covered [like Java]
I can't find the interview/presentation, but Guido Van Rossum specifically calls out Java's implementation of "exception annotations" as a demonstration of why that is a bad idea, and that it would never happen in Python. I'm not saying Guido's opinion is the absolute truth, but just letting you know that this is an explicit decision, not an unwanted shortcoming.

Statically typed Python
Personally I find working around mypy's quirks to be more effort than it's worth, so to offer another option: typeguard or beartype can be used to perform run-time type checking.

Tests aren’t enough: Case study after adding type hints to urllib3
Never checked? They're statically checked.
Also, tooling like https://pydantic-docs.helpmanual.io/ can do runtime checking for important parts of your app or you can add use this https://github.com/agronholm/typeguard to enforce all types at runtime (although I haven't measured the performance impact, probably something to do in a separate environment than production?).
