1. 
   

   import requests, re

   #regex = r"([a-zA-Z0-9_.+-]+@[a-zA-Z0-9-]+\.[a-zA-Z0-9-.]+)"
   #这个正则表达式过滤掉了qq邮箱
   regex = r"([a-zA-Z0-9_.+-]+@[a-pr-zA-PRZ0-9-]+\.[a-zA-Z0-9-.]+)"
   #基于隐私，使用了“XXXXXXXXXXXXXX”
   url = 'http://blog.sina.com.cn/s/XXXXXXXXXXXXXXXXXX.html'
   html = requests.get(url).text
   #print(html)
   emails = re.findall(regex,html)
   i = 0
   for email in emails:
   i += 1
   if i < 16:
   print("{} :{}".format(i,email))
