你好，朋友们

我不熟悉Python和Selenium，对于一个自由职业者项目，我需要创建一个web scraper，它可以自动执行从网站获取信息的手动任务。我在这里添加了代码。它应该打开一个产品页面，从下拉选项中跟踪所有可能的组合，并获取每个组合以及该产品组合的价格。最后将其写入excel文件。一个产品可能有数千种变体。每次在下拉列表中选择一个选项，价格都会更新。 我已经尝试在Selenium中使用WAIT和EXPECTED条件，但是，我继续得到异常“Message:stale element reference:element is not attached to the page document”

我已经花了足够的时间在这上面，并指望堆栈溢出社区来帮助我解决问题！在

提前谢谢！在
