driver.switch_to.frame(driver.find_element_by_tag_name("iframe"))assuming that driver is a healthy instance of webdriver. To continue with the default content do driver.switch_to.default_content()
driver.switch_to.frame(driver.find_element_by_tag_name("iframe"))假设驱动程序是一个健康的 webdriver 实例。要继续使用默认内容，请执行driver.switch_to.default_content()
EDIT: When you have switched to needed frame, locate your webelement as you always do. I guess (but not sure) in your case this will be a html/body, so
编辑：当你切换到需要的框架时，像往常一样找到你的 webelement。我猜（但不确定）在你的情况下这将是一个 html/body，所以
el = driver.find_element_by_xpath('html/body')
el = driver.find_element_by_xpath('html/body')
should be fine. And perform
应该没事。并执行
el.send_keys('keys_to_send')
el.send_keys('keys_to_send')
EDIT2: Before sending keys you may have to focus on the element (click should do the thing, a child element should appear). Or you can just place the needed text via JS.
EDIT2：在发送键之前，您可能必须关注元素（点击应该做的事情，应该出现一个子元素）。或者您可以通过 JS 放置所需的文本。
driver.execute_script('document.body.innerHTML = "%s"' % text_var)
driver.execute_script('document.body.innerHTML = "%s"' % text_var)

In order to handle iframes on a web page you need to switch to the iframes first that are present on the page using this command: driver.switch_to.frame(frame_id)

- By using name of the frame
- By using id of the frame

It uses driver.find_element_by_tag_name("iframe")statement to find iframe element which may not work or return expected iframe web element when there are multiple iframe elements in the same page.
它使用driver.find_element_by_tag_name("iframe")语句查找 iframe 元素，当同一页面中有多个 iframe 元素时，这些元素可能不起作用或返回预期的 iframe 网页元素。
There are many articles out there to explain handling iframes in detail.
有很多文章详细解释了如何处理 iframe。
