Question

我正在尝试使用序列号从2个单独的数据库中返回数据（这2个数据库对相同的物理部件使用不同的序列号格式（其中一个部件号位于实际序列号之前），因此现在我正在使用2个输入，直到我可以确认查询正常运行为止。我能够使用单个序列执行整个脚本，但是复制它只能在我尝试多个序列时读取字符串中的第一个序列。更改一些内容后，如果将输入粘贴到mySQL工作台中，则输入似乎是正确的，但脚本由于某种原因将无法读取它们。由于我在python上是新手，所以出了什么问题在我的联盟中有些出入。

我到处都在寻找答案，但是大多数人都没有使用来自用户输入的列表，所以我对如何使用该信息应用于当前问题感到困惑

如前所述，

仅适用于单个序列，而不是列表。不知道我哪里做错了。以下是pycharm控制台中的错误代码：

在mysql.connector中的where命令中使用列表
