Aprenda Task Scheduling and Awaiting Results

When working with multiple asynchronous operations, you often need to run several coroutines at the same time and collect their results once all are finished. The asyncio.gather function is designed for this purpose. It takes multiple coroutine objects and schedules them to run concurrently. When you await the result of asyncio.gather, it waits for all the coroutines to complete and returns their results as a list, in the same order as the coroutines were provided. This makes it easy to manage and use the results of several asynchronous tasks together.

        fetch_data(1),
        fetch_data(2),
        fetch_data(3)
    )
    for result in results:
        print(result)
