file contents searching

[Marktric]

Out of necessity, I am learning Python. The first project I am attempting seemed to be relatively easy when I thought of it, but has become a challenge to really get into.

What I need to do is open an unknown number of files of a certain type in a user specified directory, search for a regex string in the first file, then compare that string to each additional file and report a found/not found status in an output file.

I have been searching around, and found some of this info...that's what led me to this forum. If someone could give me a general idea of what concepts to look out for, or a tutorial suited to this application, I would greatly appreciate it.

Thanks,
Mark.

Take a look at those modules:

glob, listdir or os.path.walk+fnmatch to get the list of files.
open to read files.
re for regular expressions.

You will achieve what you want with these modules.
