`wait()` vs `as_completed()` vs `shield()`:

In Simple Words:

• as_completed(): Yields results as each task finishes, processing fastest responses first.
• wait(): Waits for tasks with return conditions (FIRST_COMPLETED, ALL_COMPLETED).
• shield(): Protects a critical coroutine from being cancelled by its caller.

# Process results as soon as each finishes:
async def process_fastest():
    tasks = [fetch_api_a(), fetch_api_b(), fetch_api_c()]
    for coro in asyncio.as_completed(tasks):
        result = await coro
        print("Got result:", result)
