jQuery火箭图标返回顶部代码

pip install selenium

# openbaidu.py
#!usr/bin/python

from selenium import webdriver
import time

browser = webdriver.Firefox()
browser.get("http://www.baidu.com")
browser.find_element_by_id("kw").send_keys("selenium")
browser.find_element_by_id("su").click()
time.sleep(5)
browser.quit()

python openbaidu.py

若selenium安装超时失败，试试国内源：

pip install -i https://pypi.tuna.tsinghua.edu.cn/simple selenium
pip install -i http://pypi.douban.com/simple/ selenium
