    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 [1] 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.

    Our plugin surfaces semantic issues in your Python code. In the example above, it detects invalid file mode being used to open the file as well as dictionary key issues. Our plugin is powered by multiple open-source tools (such as Pylint or Bandit) that surface common errors Python programmers do. By using our plugin, you not only ensure that your code adheres to good coding practices and but also detect bugs in seconds as you write code in your browser. After lots of interviews with developers, one thing that stood out was: “When it comes to reviewing the code, by the time the code hits GitHub is already too late” why? because imagine programming for 3 to 4 hours, only to be told part of your code next to be fixed. So we started working on a faster more effective way to review your code, one that catches the bug when you write it, so it’s easier for you to fix.

    Rust can do more compile-time correctness enforcement than MyPy (TypeScript-like gradual typing), Flake8, PyLint, and Bandit, which I run on save via the ALE plugin for gVim.
