Question

我是Python的新手，而且我很确定这个原因只是一个金发碧眼的时刻，但过去几天它一直在推动着我。

我一直得到“elif conName.search（line）：AttributeError：'list'对象在第106行没有属性'search'”

如果我将第54行中的模式替换为第50行中的模式，则第106-113行运行正常，但我在第114行得到相同的错误。

当我注释掉第105-123行时，代码的其余部分效果最好。

当我注释掉第106-109行时，第110-113行运行正常，但我在第114行得到了同样的错误。

我一直得到“elif conName.search（line）：AttributeError：'list'对象在第106行没有属性'search'”

这意味着此时conName是一个列表。确实在下面的两行中将conName分配给列表：

conName = ln.split("\" />")

在第一个conName.search()返回成功匹配后，您将其更改为列表，以便文件中的以下行（下一个循环迭代）conName.search产生错误。

AttributeError：基于re.compile模式
