Are multi-step workflows supported in Python?

Yes, Python Workflows allow for durable execution with automatic retries and state management using a specialized @step.do() decorator pattern.

What is the WorkerEntrypoint pattern?

It is the modern class-based structure for Python Workers that allows you to access environment bindings via 'self.env' and manage handlers like 'fetch' more effectively.

Which Python version is used in the runtime?

Cloudflare Python Workers utilize the Pyodide runtime, which supports Python 3.12+ compiled to WebAssembly.

Why does my Worker fail when using the 'requests' library?

Cloudflare Workers run in an asynchronous environment. Synchronous libraries like 'requests' block the event loop; you must use async-compatible alternatives like 'httpx' or 'aiohttp'.

Can I use external packages from PyPI with Cloudflare Python Workers?

Yes. As of December 2025, the pywrangler CLI supports deploying Workers with external dependencies defined in your pyproject.toml.
