Python 字典和正则表达式匹配用于构建URL的对象

试图从这里的pdf数据中预填充表单，我一直在使用一些正则表达式匹配对象和字典

“缩写”代码：

跳过Py2PDF部分，因为这看起来很好。请原谅我的命名习惯

### Open text file, search for field contents, and define them
with open (pdffile+'-text.txt', 'r') as text_file:

###打开文本文件，搜索字段内容并定义它们
打开（Pdfile+'-text.txt'，r'）作为文本文件：
text=text\u file.read（）
输入\u email\u value=regex.search（r'（？当然，这在之前已经得到了回答：


看起来这只是通过添加“|$”将“”默认值嵌入到我的语句中的问题
请尽可能清楚地解释你的问题。问一些具体的问题也会有帮助。你为什么要逃避？我觉得你的正则表达式很奇怪。我不确定它们是否正是你想要它们做的。例如，随机选择一个
（？=\ \ \ \）
的意思是，如果后跟this，您希望在此之前的文本匹配。而这将匹配的是一个“|”符号。很抱歉，我不清楚-我认为OR语句被忽略，因为当没有匹配时，它会抛出一个异常错误“'list'对象没有属性'group'”-我希望能够只分配“”或“”.我在逃避|因为在我知道使用DOTALL标志之前我用|替换了\n-所以它现在有点像一个分隔符。这里有一个巨大的学习曲线。
