https://github.com/Microsoft/python-language-server
`python-language-server`, a language server for Python.
Requires [.NET Core](https://docs.microsoft.com/en-us/dotnet/core/tools/dotnet-install-script) to run. On Linux or macOS:
```bash
curl -L https://dot.net/v1/dotnet-install.sh | sh
```
`python-language-server` can be installed via `:LspInstall pyls_ms` or you can [build](https://github.com/microsoft/python-language-server/blob/master/CONTRIBUTING.md#setup) your own.
If you want to use your own build, set cmd to point to `Microsoft.Python.languageServer.dll`.
```lua
cmd = { "dotnet", "exec", "path/to/Microsoft.Python.languageServer.dll" };
```
This server accepts configuration via the `settings` key.
