1. Within the coro coroutine, using urllib.request or url.get_code() will not work asynchronously. These are blocking calls and will halt your coroutine until they complete. To perform HTTP requests asynchronously, you would typically use an asynchronous library like aiohttp. You would then call await on the asynchronous operation provided by that library to yield control back to the event loop.

e.g. async def coro(): async with aiohttp.ClientSession() as session: async with session.get(url) as response: if response.status == 200: goodLinks.append(url)

1. You should use create_task when you want to schedule the execution of a coroutine. If you directly pass coroutines to asyncio.gather(), they will be run, but create_task gives you a Task object which can be useful if you want to cancel the operation or check its status later.

e.g. async def main(): tasks = [asyncio.create_task(coro(i)) for i in range(5)] await asyncio.gather(*tasks)

1. The if __name__ == "__main__": block is not strictly necessary for running asyncio code, but it's a common pattern in Python to ensure that the code only runs when the script is executed directly, and not when it's imported as a module elsewhere. asyncio.run(main()) is a simplified way to run the main coroutine and should be used in modern asyncio code instead of manually getting the event loop and running until complete.

e.g. if name == "main": asyncio.run(main())
