Grequest returns empty generators

[MadMowgli]

I have the following code:

for domain_list in chunks:
    rs = (grequests.get('https://' + url, timeout=timeout) for url in domain_list)
    grequests.map(rs)
    result_list.append(rs)

However, the generators seem to be empty:

for lst in result_list:
    print(len(list(lst)))

0
0
0
0
0

Length check is based on the following stack overflow response: https://stackoverflow.com/a/50645935/10765169

Am I doing something wrong?

Same problem

grequests.map returns the result you're looking for. It will not modify rs.

The corrected version would be something like this:

for domain_list in chunks:
    rs = (grequests.get('https://' + url, timeout=timeout) for url in domain_list)
    results = grequests.map(rs)
    result_list.append(results)
