Working on a team in a larger python application, type checkers and linters are such a time saver. It's so nice not to think about how I'd like to format my code any longer. We've made some tweaks to our ruff rules to suit the team's opinion, and now even when I don't _love_ the way it formats a particular part of code, I just move on and get something productive done instead.
And type checking is so great for both preventing bugs (which it does all the time) and self-documenting code. Can't recommend them enough.
It takes out so much frustration too. No more nitpicking about style/... in merge requests, the pre-commit hook will fix it and CI will catch it if you don't.
The more of this you can automate, the more you get to spend on "real work".
In my organisation, some co-workers used to write def func(*args,**kwargs) all the time.
That was so tiring to look for what you should put as argument. Type checking is mandatory for well organized large project.*
