This work has enabled us to further improve the performance and overall experience of other language servers, like the open-source Jedi language server (thanks to David Halter, Samuel Roeca and danixeee for their cooperation and partnership!). We’ve invested resources to standardize the way that language servers communicate with the Python extension (via Language Server Protocol). With this top of mind, our team has also been working to make language support better for everyone, regardless of your language server. However, we are committed to making sure that you can configure your development environment exactly how you like it.

We believe that Pylance provides the very best user experience for Python development and we hope that you’ll try it out. This means that you’ll get the latest and greatest language support right out of the box with the Python extension (no separate install needed!). As of this release, we’ve included the Pylance extension as an optional dependency for the core Python extension. If you’ve been following along with our releases over the last year, we’ve been making dramatic improvements to Python language support via the Pylance extension. If you’re unfamiliar with Pylance, you can read more about its awesome features in the preview release announcement blog post. This upgrade provides what we believe is the most performant and user-friendly Python editing experience for Visual Studio Code ever. Today, we’re excited to announce that the Python extension’s default language support is now powered by Pylance. Upgraded language support, powered by Pylance If you’re interested, check out the full list of improvements in our changelog. Other notable updates are that we now have faster extension startup time and a new debugger feature: live reload for Python scripts. We’re thrilled to announce that Pylance is now the default language server for Python and is bundled with the core Python extension as an optional extension starting with this release. You can learn more about Python support in Visual Studio Code in the documentation. If you already have the Python extension installed, you can also get the latest update by restarting Visual Studio Code.

You can download the Python extension from the Marketplace, or install it directly from the extension gallery in Visual Studio Code. We are pleased to announce that the May 2021 release of the Python Extension for Visual Studio Code is now available.
