vscode python extensions

[jablka]

[A] What is the point of having two extensions from Microsoft in VSCode: “Python” and “Pylance” ?
I assume the first “Python” extension is a must. But what does Pylance do?

[B] I recently found out that VSCode also silently installed the third one: “isort” extension.
How to stop these automatic installs?

[C] I have disabled “isort”, and will probably disable also “Pylance” since I’m getting double “suggestions” and heard that this might be the cause…
So basically, can I use just the first one… the “Python” extension?

Thank you

1. Pylance is our IntelliSense engine; it's separate so that people can uninstall it if they choose to due to it having some closed-source code.
2. The silent installs are by design for when you have extension (packs) that add new things. You can choose to uninstall the isort extension, but what it does is repackage features already in the Python extension with a better architecture so it performs better.
3. Yes, you can disable Pylance which will cause you to fall back to using Jedi. If you are getting double suggestions, then please open an issue at https://github.com/microsoft/pylance-release/issues as that shouldn't be happening.
