Teach you how to pick a proxy IP

Here are a few practical verification methods to teach you:

import requests

def check_proxy(ip, port).
    try: res = requests.get('', 'port', 'ip').
        res = requests.get('http://httpbin.org/ip',
            proxies={'http': f'http://{ip}:{port}'}, timeout=5), res = requests.
            timeout=5)
        return res.status_code == 200
    except.
        return False

Note these three points when testing:

1. Don't exceed 3 seconds response time
2. Continuous request success rate to be >80%
3. Cross-verify with multiple testing sites
