Async Support - HTTPX (via) HTTPX is the new async-friendly HTTP library for Python spearheaded by Tom Christie. It works in both async and non-async mode with an API very similar to requests. The async support is particularly interesting - it's a really clean API, and now that Jupyter supports top-level await you can run (await httpx.AsyncClient().get(url)).text directly in a cell and get back the response. Most excitingly the library lets you pass an ASGI app directly to the client and then perform requests against it - ideal for unit tests.
