| Is there any study that shows that typing in Python improves code quality and reduce runtime issues? |

| That's equivalent to asking if there are benefits of static typing. |

Python type checking is also AOT, but (unlike where it is inextricably tied to compilation because types are not only checked but used for code generation) it is optional to actually do that step. Python type annotations exist and are sometimes used at runtime, but not usually at that point for type checking in the usual sense. | | |

In fact, Haskell then allows you to add back in runtime types using Typeable! https://hackage.haskell.org/package/base-4.21.0.0/docs/Data-... |

| Well, it's just a documentation suggestion for user. Having for me about same value as if it was written in pydoc. I'd really love to see such study as well |
| |
| ▲ | sails01 6 days ago | parent [-] | | Agree, we already had a solution documenting types in docstring. In my case they just add noise when reading code and make it more difficult to review |
