Async for loops in Python

Video Description

Await for it! A deep dive into the purpose of the async for loop in Python. How to use the async for loop, why to use the async for loop, and how to write your own async iterators using both async generators as well as by learning the async iterator protocols and writing your own async iterator. We'll see an example ASGI app that computes the SHA256 hash of an uploaded file using Starlette and uvicorn, and write a test client using httpx. Then we implement a simple rate limiter. ― mCoding with James Murphy (https://mcoding.io) Source code: https://github.com/mCodingLLC/VideosSampleCode Starlette: https://github.com/encode/starlette FastAPI: https://github.com/tiangolo/fastapi Httpx: https://github.com/encode/httpx Uvicorn: https://github.com/encode/uvicorn SUPPORT ME ⭐ --------------------------------------------------- Sign up on Patreon to get your donor role and early access to videos! https://patreon.com/mCoding Feeling generous but don't have a Patreon?
