#  Start the browser driver server 
driver = webdriver.Chrome()
driver.get("https://mail.qq.com/")
driver.maximize_window()

#  cut iframe, adopt name Property Toggle 
driver.switch_to.frame("login_frame")


#  Navigate to the account input box 
locator2 = (By.XPATH, '//input[@id="u"]')
ele2 = WebDriverWait(driver=driver, timeout=10, poll_frequency=1).until(
    EC.visibility_of_element_located(locator=locator2))
ele2.send_keys("[email protected]")

time.sleep(5)
driver.quit()
