How to use the pyppeteer.page.Page.Events function in pyppeteer

               lambda event: self.emit(Page.Events.RequestFinished, event))

               lambda event: self.emit(Page.Events.Response, event))
        _nm.on(NetworkManager.Events.RequestFailed,

def closed(fut: asyncio.futures.Future) -> None:
            self.emit(Page.Events.Close)
            self._closed = True

def _emitMetrics(self, event: Dict) -> None:
        self.emit(Page.Events.Metrics, {
            'title': event['title'],
            'metrics': self._buildMetricsObject(event['metrics']),
        })

               lambda event: self.emit(Page.Events.FrameAttached, event))
        _fm.on(FrameManager.Events.FrameDetached,

               lambda event: self.emit(Page.Events.FrameDetached, event))
        _fm.on(FrameManager.Events.FrameNavigated,

def _onDialog(self, event: Any) -> None:
        dialogType = ''
        _type = event.get('type')
        if _type == 'alert':
            dialogType = Dialog.Type.Alert
        elif _type == 'confirm':
            dialogType = Dialog.Type.Confirm
        elif _type == 'prompt':
            dialogType = Dialog.Type.Prompt
        elif _type == 'beforeunload':
            dialogType = Dialog.Type.BeforeUnload
        dialog = Dialog(self._client, dialogType, event.get('message'),
                        event.get('defaultPrompt'))
        self.emit(Page.Events.Dialog, dialog)

                  lambda event: self.emit(Page.Events.Load))
        client.on('Runtime.consoleAPICalled',

               lambda event: self.emit(Page.Events.RequestFailed, event))
        _nm.on(NetworkManager.Events.RequestFinished,
