selenium模块唯一的缺点就是占内存，运行慢，好处就是入门爬取js数据简单

from selenium import webdriver
from bs4 import BeautifulSoup


# 爬取百度今日热点
url = 'http://top.baidu.com/buzz?b=341&c=513&fr=topbuzz_b1'

browser = webdriver.PhantomJS()
browser.get(url)
soup = BeautifulSoup(browser.page_source, 'lxml')

# 标题
title = [i.get_text().strip() for i in soup.select('tbody tr .keyword .list-title')]
# print(title)

# 搜索指数
inde = [i.get_text().strip() for i in soup.select('tbody tr .last')][1:]
# print(inde[1:])

# 传送url
url_texi = [i.get('href') for i in soup.select('tbody tr .keyword .list-title')]
# print(url_texi)


for t, ie, u_t in zip(title, inde, url_texi):
    print('标题：{}，热度：{}，传送：{}'.format(t, ie, u_t))

input('按回车键退出。。。')
