Ive been using Python for +16 years. Most of that time, my development was using Vim with no sort of autocompletion or even a linter. After a few years away from Python, I'm back heavy into it, currently using 3.7. I have totally embraced type hints and automatic linting in an IDE (mostly use PyCharm, but sometimes Vs code). I was always pretty productive with Python, but type hints have made me even more productive. (It also helps that I'm currently doing green field development). I like that they're optional and not enforced. However, I also like that my IDE visually indicates when I've violated that contract. Has boosted my effectiveness quite a bit. Ive defaulted to type hints almost everywhere, especially in any library code I write (I also try and write useful docstrings). For me, its especially important because I'm the most senior Python dev on the team, the other 5 are experienced devs, but just learning Python. Me taking the time to do the type hints and docstrings is immensely helpful to them, as they all come from statically typed languages. That said, this is my opinion. That's what this "argument" comes down to. Arguing over opinions and tastes. Each has their own and their own reasoning. Doesn't make either side right or wrong. Id just say go in whatever direction works best for one's self or team. There's no one size fits all solution.
