Type hints are optional. Type hints are very different to a strongly typed language with a good type system. Haskel as an extreme feels like algebra, you have a type a, you need a type c, you have a function a to b, and a function b to c, you just compose them together and from your a you have a b. Tools like hoogle can tell you the function to use for the given args to get to the final type you want. Ignoring Haskel even Typescript can let you express things hard to express in Python with ADT’s etc. Docker has nothing to do with Python but if you want to produce an artifact you can just run anywhere it solves the dependency issue in that the decencies are in the image and you don’t need to run pip install on a deployment server.
