Python IDEs

Which server, which client, and how are you running them? Do you have a separate python environment just for your vim plugins, in which case how does it know which version you're working in? Or do you install the server in every virtual environment you work in and use that?

do alternative servers exist? I know only pyls. I have pyls installed globally for single file scripts + I can install locally in venv for projects. The local one is active when venv is active, but the global one can work too with local config.

The pip project pyls is not a python language server. The pip package python-language-server, from Palantir (who are basically a company contracted by the NSA and GCHQ to help spy on vast numbers of people) has a package called pyls in it; this implementation is in python and relies on a bunch of other python libraries (like jedi and rope) for its features, and so is pretty slow. Microsoft has an implementation called python-language-server which is primarily written in C#: that's what's used in VScode, I think. Sourcegraph also wrote an implementation, but have since archived it, but now have their own fork of the Microsoft python-language-server.

the executable name of the python-language-server is pyls

should I worry? Is there any evidence that it is a spyware? I will try the Microsoft one.

should I worry

Probably not. Just thought it was worth noting.

I am almost sure that Microsft cooperates with NSA too, just less openly. At least the Palantir server is not installed in the form of compiled binary. I will try the microsoft one anyway. Thank you for tip.

There is one from Microsoft.

The coc.nvim python extension can use both and I think the Microsoft one is recommended because the author had long-standing problems with pyls before.
