Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

How to fix mypy warning for this function
2 projects | reddit.com/r/learnpython | 26 Oct 2021
For your interest, this indeed was unintended behaviour on the part of `mypy`. It has since been fixed, apparently: https://github.com/python/mypy/pull/111532 projects | reddit.com/r/learnpython | 26 Oct 2021
Just created a bug report for this. https://github.com/python/mypy/issues/11390

I am seeing what the GP comment says in a codebase I manage, around 47k LOC. Not massive at all, but enough where the problems mentioned above start to pop up. This is an application that runs in servers to analyze traffic data, so it has both analysis code and also a lot of code for the analysis framework. It gets hard to manage. I have unit tests and also integration tests that cover some, but not all of the code paths (it's very hard in this case to have everything covered). Most of the times, when they fail is due to something that would have been caught by static typing.
The codebase is being slowly migrated to static typing. On one hand, as the parent says, the typing module is still immature and there are still some Python constructs (not too weird ones, see  for an example) that you can't type-check correctly. On the other hand, I like the fact that you can include typing slowly and not all at once, it makes the effort much easier to tackle. And, if typing works, it works well.
Regarding performance, well. Parallelism is pretty hard to do well, and the language itself is not the fastest thing. Some parts are migrated to a C extension but that's costly in terms of development and debugging time.
Despite all of that, I do think that Python was the best choice for our situation, and still is. Maybe from this point onwards another language would make things easier, but without Python's library support, ease and speed of development and expressiveness the cost of just getting to market would have been far higher, and probably we wouldn't have reached this point with other languages. And migrating the codebase to another language is just not worth it at all, as there are still a lot of areas we can improve quite a lot with far less effort than a full rewrite.

I don't know where you're getting your information, they did implement it. It's possible you're thinking of this issue which would make the typing more precise and let you specify totally different types for different keys. For now though any of the 4 ways I gave works.

Is there any language that is as similar as possible to Python in syntax, readability, and features, but is statically typed?

It doesn't look like it. The best way to view the hierarchy right now, I believe, is to look at the system/exceptions.nim file.
