用法：
1、先导入Select类
from selenium.webdriver.support.select import Select
2、实例化，通过源码可知初始化对象的时候需要传入下拉框元素对象：
3、示例代码
#form2.html
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> </head> <body> <form action="javascript:alert('test')"> 省份： <select id="province" > <option value="bj">北京市</option> <option value="tj">天津市</option> <option value="sc">四川省</option> <option value="sd">山东省</option> <option value="hn">河南省</option> </select> </form> </body> </html>
测试代码
