switch_to.parent_frame()和switch_to_default_content()的帧数有所不同。它们在下面列出-
switch_to_parent_frame()
该方法用于出现在当前框架之外，然后我们可以访问该框架外部而不是该框架内部的元素。这样就切换了控制；外部可以是网页的其他框架或一部分。这样我们就可以脱离当前框架。
语法-
driver.switch_to.parent_frame();
switch_to_default_content()
此方法用于从所有帧中移出并在页面上切换焦点。一旦我们搬出，它将无法访问页面中框架内的元素。
语法-
driver.switch_to_default_content();
使用switch_to_default_content()方法的代码实现。
from selenium import webdriver
driver = webdriver.Chrome(executable_path="C:\\chromedriver.exe")
# to maximize the browser window
driver.maximize_window()
#get method to launch the URL
driver.get("https://the-internet.herokuapp.com")
#to refresh the browser
driver.refresh()
driver.find_element_by_link_text("Frames").click()
driver.find_element_by_link_text("Nested Frames").click()
# to switch to frame with frame name
driver.switch_to.frame("frame-bottom")
# to get the text inside the frame and print on console
print(driver.find_element_by_xpath ("//*[text()='BOTTOM']").text)
# to move out the current frame to the page level
driver.switch_to.default_content()
#to close the browser
driver.quit()使用switch_to_parent_frame()方法的代码实现。

# to get the text inside the frame and print on console

# to move out the current frame to the parent frame
driver. switch_to_parent_frame()
#to close the browser
driver.quit()
