My Python Development Environment, 2020 Edition 2 months, 2 weeks ago

For years I’ve noodled around with various setups for a Python development environment. A couple of years ago I wrote about a setup I finally liked; this is an update to that post. Bad news: this stuff still isn’t stable, and I’ve had to make some changes. Good news: the …
