使用Python从下拉菜单中进行抓取

我是Python的新手，尝试在Python中检索数据 使用Python版本3.6.0

有两个下拉列表，第二个下拉列表的数据取决于第一个下拉列表的选择

首先：“Adi组织” 秒：“UEVCB Adi”

源中的所有选项如下所示：

<option value="0" selected="selected">TÜMÜ</option> #this is default value when we open the page
<option value="10374">1461 TRABZON ELEKTRİK ÜRETİM A.Ş</option>
<option value="9426">2M ELEKTRİK ÜRETİM SANAYİ VE TİCARET ANONİM ŞİRKETİ</option>

通过这个代码，我们可以选择从第一个下拉使用搜索功能和输入键

说到第二个，它会生成

ImportError:sys.meta\u路径为None，Python可能会关闭

我该怎么处理

谢谢。

您的代码似乎对

StaleElementException

以及异常敏感，

元素在点处不可单击…

。请尝试下面的网页抓取部分代码，并告诉我结果：
