from itertools import cycle

proxy_pool = cycle([
    'http://user:pass@sg01.ipipgo.net:30001',
    'http://user:pass@sg02.ipipgo.net:30001', ...
    ... Other nodes
])

for _ in range(10).
    proxy = next(proxy_pool)
    try.
        response = requests.get('https://target.com',
                             proxies={"http": proxy, "https": proxy}, timeout=8)
                             timeout=8)
        print(f "Successful access using IP:{proxy}")
    except.
