1. asyncio is single threaded execution, using await to yield the cpu to other function until what is await'ed is done.

    import asyncio async def my_func(t): print("Start my_func") await asyncio.sleep(t) # The await yields cpu, while we wait print("Exit my_func") async def main(): asyncio.ensure_future(my_func(10)) # Schedules on event loop, we might want to save the returned future to later check for completion. print("Start main") await asyncio.sleep(1) # The await yields cpu, giving my_func chance to start. print("running other stuff") await asyncio.sleep(15) print("Exit main") if __name__ == "__main__": asyncio.run(main()) # Starts event loop
