selenium 搭配python多线程

from selenium import webdriver


from time import sleep, ctime
import threading

     else:
         #因为没有ie驱动,所以和其他的浏览器一样,都让他默认为chrome
         print("browser 参数有误,默认转为谷歌")
         driver = webdriver.Chrome()


     driver.get("http://www.baidu.com")
     driver.find_element_by_id("kw").send_keys(search)
     driver.find_element_by_id("su").click()
     sleep(2)
     driver.quit()

if __name__ == '__main__':
     # 启动参数（指定浏览器与百度收缩内容）
     lists = {'chrome': 'threading',"ie":"ssjs" ,'firefox': 'python'}
     threads = []
     files = range(len(lists))
     print(files)

     # 创建线程
     print(lists.items())
