Try this:

   x, y, z = map(files.find, ['this', 'that', 'the-other'])

or, if you're just trying to find the first match:

  re.search('this|that|the-other', files).start()


OTOH, you've hinted at an application that may not
appropriate for multiple string searches.  Instead, look
at building a dictionary or list of files -- they are most
easily searched and better suited for associating other
data such as file sizes, etc.
