await make_request(). A close sibling is asyncio.run(), which executes a coroutine and blocks until complete. The main entry point for asyncio programs. A close sibling is asyncio.sleep(), which pauses execution of the current coroutine for the given seconds. A close sibling is asyncio.gather(), which runs multiple coroutines concurrently and returns their results. A close sibling is asyncio.create_task(), which schedules a coroutine to run as a Task, returning a Task object.
