1. Please don't top post, this is usenet, we don't top post, comments go 
after the text they comment on soi we can read down the page and it makes 
sense.

2. You gave the thread the title of "regex python help".

3. Your initial comment was "I am creating a tool to search a filesystem 
for one simple string."

4. The tool (see 3) already exists, it's called grep, it uses regular 
expressions (see 2). It's also going to be a lot faster than using python.

5. According to your post, grep seems to be the tool you are looking for.

6. Reinventing grep in python seems much more silly to me, by the time 
you've finished writing and testing the python code (especially if you 
need to seek help from a newsgroup in the process) grep would have found 
and identified every file containing your "one simple string".
