一个循环的示例

import time
import requests
from bs4 import BeautifulSoup


def loop():
    while True:
        sission = requests.Session()
        r1 = sission.get('http://xwb2.w113.idchz.com/index.php/archives/25/')
        soup = BeautifulSoup(r1.text, 'html.parser')
        titel = soup.find(
            name='a', attrs={'href': 'http://xwb2.w113.idchz.com/index.php/archives/25/'})
        a = titel.get_text('')
        a = int(a)
        # print(a)
        if a == 1:
            time.sleep(2)
            print('1')
            continue
        elif a == 2:
