How to approach it

They're checking whether you understand asyncio's cooperative multitasking model: a coroutine itself hands control to the event loop at await points, and any blocking call stops the entire application.

Write an async function fetch_all that takes a list of URLs, an async function that fetches a single URL, and a limit on concurrent requests. It returns the results in the same order as the URLs, and a failure of one request must not take down the others.
