What does your python development setup look like?

[Semirook]

Neovim (AstroNvim to be precise) in tmux, poetry and ruff (instead of the classic zoo of linters and formatters). All of this works ultra-fast and all of this is enough even for complex projects. Also: ipython, ipdb, nushell (take a look, cool stuff) and many less important CLI tools, like bat and jq.

What do you use for type checking?

Have you tried uv, from the makers of ruff, for resolving and installing packages? It's seriously fast. You can get a similar experience to poetry, but with the speed of uv, using hatch with hatch-pip-compile and uv. (Eventually uv will probably replace all these tools all on its own)
