Python how to handle exception?

Question

Python

Tell me how to handle the exception

import requests
from proxy_list import runproxy

def check():
  httproxy = {"http": "http://" + runproxy()}
  request_handler = requests.get('http://www.yandex.ru', proxies=httproxy)
try:
  check()
except Exception, e:
  check()

in this code, runproxy() returns a random proxy from the checked proxy list, but since proxies tend to die all the time, I would like to add another level of verification. if any request fails, you need to call runproxy() to get another proxy and make the request again, and continue this until the request passes or until a certain number of attempts

Answer 1

while True:
    try:
        check()
    except Exception, e:
        continue
    break

Answer 2

def check(): 
    httproxy = {"http": "http://" + runproxy()}
    result = requests.get('http://www.yandex.ru', proxies=httproxy)
    if status_code == 200:
        return httproxy

good_proxy = None
while not good_proxy:
    good_proxy = check()

Answer 3

if request_handler.status_code != 200:...
