Python has excellent string methods. There seems to be a split between people who first always grab regex for string parsing, and those who might not. If you go with your regex, I think you can comment what you have and move on. I glaze over looking at regexes. That's just me. The code to first search for "Msg-", then check what follows would take a couple of lines, but might be easier to understand later. I've been writing python for a couple of years, and although I feel comfortable with it, there is much more more me to learn. One thing I have learned over many years of programming is that figuring out what a piece of code is trying to accomplish takes more time than writing it originally. Do you really want to match "Msg-iD" (lower case i)? Or are you only allowing "ID" or "Id"? > > Not that I'm aware of. > > > the regex should match Msg-id:, Msg-Id, ... but not msg-id: and so on. > > What's the use-case for this? > > The way I would typically do something like this is build my regexes in > all lower case and .lower() the text I was matching against them.
