如何从字典列表中收集任务 aiohttp async python

Question

I have the following list of dictionary:

[{'id': 1, 'url': 'https://url1.com'}, {'id': 2, 'url': 'https://url2.com'} , {'id': 3, 'url': 'https://url3.com'}]

How to use asyncio.gather to pass id and url to a sync method ?

ideally something like this:

asyncio.get_event_loop().run_until_complete(
        asyncio.gather(*[process(id, url)])) # process is another async method which will need id and url separately

if I just had a list of url then I know I could easily do something like this:

asyncio.get_event_loop().run_until_complete(
        asyncio.gather(*[process(url) for url in url_list]))

A list comprehension would produce your list of URLs. Something like:

x = [{'id': 1, 'url': 'https://url1.com'}, {'id': 2, 'url': 'https://url2.com'} , {'id': 3, 'url': 'https://url3.com'}]
urls = [a_dict['url'] for a_dict in x]

If you want id and url then extract them as a list of tuples:

 [ (a_dict['id'], a_dict['url']) for a_dict in x]
 >>>> [(1, 'https://url1.com'), (2, 'https://url2.com'), (3, 'https://url3.com')]
