python版本的puppeteer叫pyppeteer，

pip install pyppeteer
pyppeteer-install #安装chromium

然后配置Python36\Lib\site-packages\pyppeteer\connection.py，第43行添加两个参数

self._ws = websockets.client.connect(self._url, max_size=None, loop=self._loop, ping_interval=None, ping_timeout=None)

解决报错： pyppeteer.errors.NetworkError: Protocol Error (Runtime.callFunctionOn): Session closed. Most likely the page has been closed.
