print(fuc("1.txt"))

2 定义一个函数func(urllist)   urllist:为URL的列表，例如：[‘http://xx.com’,’http://www.xx.com’,’http://www.xxx.com’…]

import logging,urllib.request
logger = logging.getLogger()
hdlr = logging.FileHandler('sendlog.log')
formatter = logging.Formatter('%(asctime)s %(levelname)s %(message)s')
hdlr.setFormatter(formatter)
logger.addHandler(hdlr)
logger.setLevel(logging.NOTSET)
def func(urllist):

    for i in urllist:
        try:
            f=urllib.request.urlopen(i)
        except Exception as e:
