Process list of async tasks immediately upon each task's completion












0















How can I process the results of a list of async tasks immediately as a task is completed?



For instance, the following should display whichever page loads first:



urls = ['stackoverflow.com', 'google.com']
tasks = [asyncio.create_task(fetch_page(x)) for x in urls]

for page in asyncio.give_me_results_ASAP(tasks):
print(page.url)


Since google loads faster, I'd like it to print:



google.com
stackoverflow.com

  • Can you explain your priorities a bit more? Is the order the most important thing to you, or the immediacy? If the immediacy is the primary goal, why is it the goal? Would you be open to solutions that get the work done faster even if they sacrifice ordering?

  • @BearBrown That's a good point. Though I suppose I had some sort of asynchronous iterator in mind. (That way, I can tee out the results in a thread-safe manner but also process them immediately.)
