I agree that the ecosystem is a bit messy, but it's more of a function of how long Python has been around, and how successful it has been. Newer languages have the benefit of hindsight. Take `go fmt` or `cargo fmt`. black is the de facto autoformatter, but it's still an optional dependency. Maybe like virtualenv it'll eventually be integrated into the standard library/distro. That would help. With other stuff, the split you describe could be a real problem, although for the majority of Python users, using mypy and poetry is fine. > basically the company I was working for mandated they were not going to ever upgrade to python 3 because of the effort required and thus stopped all migration related projects If you're actually serious, this is intriguing to me. Business-wise, I have never seen the math shake out this way. When we've done sizings/estimated developer hours and ROI, it's always been more economic to slowly migrate to Python 3 vs a rewrite, even if the dev team is also already using and well-versed in another language. If you're able to provide more details, please do. It's so rare to have a high-quality discussion about this.
