我需要使用正则表达式re.findall（）或re.multiline（）来解析此库存日志中的任何数字有什么建议吗？这是我到目前为止所拥有的。
以下是库存日志的示例：

不要使用正则表达式进行解析。除了要求上下文的PCRE版本外，它们还是slow when used like this。您是否考虑过使用Ply？你正在努力推动自己的状态机，以及其中的痛苦。
我有一个sample ply parser你可以用来开始。了解它如何在lexer.py文件中使用简单的正则表达式来定义令牌，这些令牌将被传递到parser.py文件。解析器定义令牌的有效顺序，以及如何处理令牌集。
这允许您在解析器中找到匹配时执行代码，在词法分析器和中确定上下文时。例如，您在词法分析器中找到一个数字，并将其传递给解析器。解析器看到数字标记位于处理器标记之后，并将其记录为相关数据。
