In what way is grequests asynchronous?

Question

I\'ve been using the python requests library for some time, and recently had a need to make a request asynchronously, meaning I would like to send off the HTTP request, have

Answer 1

Create a list of requests and then send them with .imap:

event_list = [grequests.get(url_viol_card, params={"viol": i},
              session=session) for i in print_ev_list]
for r in grequests.imap(event_list, size=5):
    print(r.request.url)

• session is requests.Session() object (optional)
• size=5 send 5 requests simultaneously: as soon as one of them is completed the next one is sent
• In this example when any request (unordered) is completed its url is printed
