我是Python的新手，我很确定这仅仅是一个金发女郎的时刻，但这几天我一直被它逼疯了 我一直在第106行看到“elif conName.search（line）：AttributeError:'list'对象没有属性'search'” 如果我将第54行中的模式替换为第50行中的模式，那么第106-113行运行良好，但在第114行得到相同的错误Regex AttributeError：基于重新编译模式,regex,python-3.x,Regex,Python 3.x,我是Python的新手，我很确定这仅仅是一个金发女郎的时刻，但这几天我一直被它逼疯了 我一直在第106行看到“elif conName.search（line）：AttributeError:'list'对象没有属性'search'” 如果我将第54行中的模式替换为第50行中的模式，那么第106-113行运行良好，但在第114行得到相同的错误 ## This should be line 19 html_doc = """ <title>Flickr: userna

我一直在第106行看到“elif conName.search（line）：AttributeError:'list'对象没有属性'search'”
这意味着此时conName
是一个列表。实际上，下面两行将conName
分配给列表：
conName = ln.split("\" />")
在第一次conName.search（）
返回一个成功匹配后，您将其更改为一个列表，因此对于文件中的以下行（下一次循环迭代）conName.search
会产生错误
