Question

因此，我为亚马逊网站编写了一个网站自动化的小脚本，这只是一个测试脚本，我知道由于最低的可能性，这些礼品卡代码都不会有效，但是当我检查很多一段时间后出现回溯错误并停止代码。想知道如何解决

我已经进行了一些研究，并且尝试了一些尝试，但当我使用except时：通过它只是继续执行代码并且不保持检查代码，我希望如果出现错误，它将继续在正确的地方检查代码它离开了，或者帮我解决错误:) 编辑：我还没有看到这个问题是重复的，我为什么要问它，为什么它不同于其他问题？我想知道为什么会发生特定的错误，为什么以及如何使它在发生错误时始终在正确的位置检查代码左，谢谢：）

time.sleep(5)
for i in range(int(howmany)):
    randomthreenumber = str(random.randint(0,9))+str(random.randint(0,9))+str(random.randint(0,9))

    driver.find_element_by_class_name("pmts-claim-code").send_keys(Keys.CONTROL + "a");

    time.sleep(0.5)
    checked = "CODE CHECKED"
    print (checked)
print("WE ARE DONE CHECKING YOUR CODES!!")

错误：

selenium.common.exceptions.StaleElementReferenceException: Message: stale element reference: element is not attached to the page document

期望的结果保持检查代码没有错误吗？
