python com编程 控制IWebBrowser2 Internet Explorer 问题

功能：
1， 获得IE浏览器句柄
2， 使用句柄利用pythoncom 连接到IE浏览器，并且获得浏览器对象和Document对象
3， 通过IE浏览器对象控制浏览器，先导航到百度， 然后试着去寻找搜素input ： ‘kw’
出错语句：dom.getElementById('kw')
TypeError: getElementById() takes 1 positional argument but 2 were given
代码 （运行前需要手动打开IE）

Traceback (most recent call last):

x=dom.getElementById('kw')
TypeError: getElementById() takes 1 positional argument but 2 were given
错误语句：
x=dom.getElementById('kw')
看起来python在调用getElementById时候把此方法当成类方法，默认传入self参数，但是此方法并不接受self，所以报错
这个问题如何解决，有没有大神来看看
