感谢下面可爱的评论，我编辑了这段代码，但我得到了同样的错误，如下所示：
Message: stale element reference: element is not attached to the page document
我大致理解为什么会出现此消息，但仍然不清楚如何解决此问题。我将非常感谢任何评论！提前谢谢了！
这就是我想出来的。但我不确定代码是否正确。我不懂蟒蛇。
#get select
select1 = Select(driver.find_element_by_xpath('//select[@name="sido"]'))
#get all options from select
options1 = select1.options
for opt1 is options1:
#select the option which has the value of opt1
select1.select_by_value(opt1.get_attribute("value"))
time.sleep(5)
select2 = Select(driver.find_element_by_xpath('//select[@name="gugu"]'))
options2 = select2.options
for opt2 in options2:
select1.select_by_value(opt2.get_attribute("value"))
time.sleep(4)
