from selenium import webdriver
import time
from pyquery import PyQuery as pq
from lxml import etree

driver = webdriver.Ie()
driver.maximize_window()    #浏览器窗口最大化
driver.get("https://www.toutiao.com/")
driver.implicitly_wait(10)


driver.find_element_by_link_text("科技").click()
driver.implicitly_wait(10)

time.sleep(5)
page = driver.page_source    #page_source方法可以直接返回页面源码
doc = pq(page)
doc = etree.HTML(str(doc))
contents = doc.xpath('//div[@class="wcommonFeed"]/ul/li')

for x in contents:
    title = x.xpath('div/div[1]/div/div[1]/a/text()')
    if title:
        title = title[0]
        print(title)
    else:
        pass
