使用Python批量判断网站是否可以访问

学校的IPV6经常莫名其妙自己断开，所以想到自动判断IPV6的网站是否可以访问，如果监测到网站无法访问了，就自动连一下网。美滋滋。

import requests
from requests.packages.urllib3.exceptions import InsecureRequestWarning
import io
import sys
sys.stdout = io.TextIOWrapper(sys.stdout.buffer, encoding='utf-8')
requests.packages.urllib3.disable_warnings(InsecureRequestWarning)
f = open('url.txt', 'r')
url = f.readlines()
length = len(url)
url_result_success = []
url_result_failed = []
for i in range(0, length):
    try:
        response = requests.get(url[i].strip(), verify=False, allow_redirects=True, timeout=5)
        if response.status_code != 200:
            raise requests.RequestException(u"Status code error: {}".format(response.status_code))
    except requests.RequestException as e:
        url_result_failed.append(url[i])
        continue
    url_result_success.append(url[i])
f.close()
result_len1 = len(url_result_failed)
result_len2 = len(url_result_success)
for i in range(0, result_len1):
    print(url_result_failed[i].strip() + "打开失败")
print("   ")
for j in range(0, result_len2):
    print(url_result_success[j].strip() + "打开成功")

url.txt里面就放入网址列表就行了
