Codeium and Pylance are two Visual Studio Code extensions that speed up Python development: Codeium suggests and generates code as you type, and Pylance highlights errors in your code before you run it. Install both together for a much smoother coding workflow.

What you need

  • Visual Studio Code, downloaded from code.visualstudio.com.
  • A Google account (or any account) to sign in to Codeium, or a Codeium account created directly.

Steps

1. Install Codeium

  1. Open the Extensions tab in the sidebar of VS Code.

  2. Search for Codeium.

  5. Start typing code or a comment describing what you want. Codeium suggests a completion inline; press Tab to accept it. If you don’t like the suggestion, keep typing and it disappears.
