Description:
 def render(self, retries: int = 8, script: str = None, wait: float = 0.2, scrolldown=False, sleep: int = 0, reload: bool = True, timeout: Union[float, int] = 8.0, keep_page: bool = False):
 """Reloads the response in Chromium, and replaces HTML content with an updated version, with JavaScript executed. :param retries: The number of times to retry loading the page in Chromium. :param script: JavaScript to execute upon page load (optional). :param wait: The number of seconds to wait before loading the page, preventing timeouts (optional). :param scrolldown: Integer, if provided, of how many times to page down. :param sleep: Integer, if provided, of how many long to sleep after initial render. :param reload: If ``False``, content will not be loaded from the browser, but will be provided from memory. :param keep_page: If ``True`` will allow you to interact with the browser page through ``r.html.page``. If ``scrolldown`` is specified, the page will scrolldown the specified number of times, after sleeping the specified amount of time (e.g. ``scrolldown=10, sleep=1``). If just ``sleep`` is provided, the rendering will wait *n* seconds, before returning. If ``script`` is specified, it will execute the provided JavaScript at runtime. Example: .. code-block:: python script = \"\"\" () => { return { width: document.documentElement.clientWidth, height: document.documentElement.clientHeight, deviceScaleFactor: window.devicePixelRatio, } } \"\"\" Returns the return value of the executed ``script``, if any is provided: .. code-block:: python {'width': 800, 'height': 600, 'deviceScaleFactor': 1} Warning: the first time you run this method, it will download Chromium into your home directory (``~/.pyppeteer``).
