Day7：requests 获取网页标题

`import requests
from html.parser import HTMLParser

class TitleParser(HTMLParser):
def handle_starttag(self, tag, attrs):
if tag == "title":
self.in_title = True
def handle_data(self, data):
if getattr(self, "in_title", False):
print("标题:", data)
self.in_title = False

url = "https://www.cnblogs.com"
r = requests.get(url)
parser = TitleParser()
parser.feed(r.text)`
知识点： 安装第三方库 requests、发送 GET 请求、提取 HTML 标题
