Vouch Request - Add pythonVersion option to pythonExtension (#3154) #3156
Description
Why do you want to contribute?
I came across issue #3154 while exploring the trigger.dev codebase and noticed it's a well-scoped, beginner-friendly fix. The pythonExtension() function currently hardcodes python3 installation without any version pinning, which causes compatibility problems for users who need a specific Python version (e.g., 3.12 for newer packages or 3.10 for legacy dependencies).
The fix is straightforward, adding a pythonVersion option to PythonOptions and conditionally generating Dockerfile instructions using the deadsnakes PPA. I've already traced through the relevant code in packages/python/src/extension.ts and have a clear implementation plan. I'd love to get this merged as my first contribution to trigger.dev.
