Python:提取网页中的电子邮箱
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))
