用python爬取微博热搜数据并保存

主要用到requests和bf4两个库
将获得的信息保存在d://hotsearch.txt下

import requests;
import bs4
mylist=[]
r = requests.get(url='https://s.weibo.com/top/summary?Refer=top_hot&topnav=1&wvr=6',timeout=10)
print(r.status_code)  # 获取返回状态
r.encoding=r.apparent_encoding
demo = r.text
from bs4 import BeautifulSoup
soup = BeautifulSoup(demo,"html.parser")
for link in soup.find('tbody') :
    hotnumber=''
    if isinstance(link,bs4.element.Tag):
#        print(link('td'))
        lis=link('td')
        hotrank=lis[1]('a')[0].string#热搜排名
        hotname=lis[1].find('span')#热搜名称
        if isinstance(hotname,bs4.element.Tag):
            hotnumber=hotname.string#热搜指数
            pass
        mylist.append([lis[0].string,hotrank,hotnumber,lis[2].string])
f=open("d://hotsearch.txt","w+")
for line in mylist:
    f.write('%s %s %s %s\n'%(line[0],line[1],line[2],line[3]))
