Did you know you can write Python directly inside the Google Earth Engine code editor — no notebooks, no local install? In this video I test the Open Earth Engine Extension (OEEex), a Chrome extension that brings a full Python runtime into GEE via Pyodide.
✅ What's covered:
→ What the Open Earth Engine Extension is and how it works
→ How Python runs in the browser via Pyodide (WebAssembly)
→ Installation and activation — including the Chrome version gotcha
→ The rules for writing Python files in GEE
→ Full NDVI analysis demo in Python syntax inside the GEE editor
→ Honest assessment: what works, what to be careful about
