Python how to implement something like .gitignore behavior

I need to list all the files in the current directory (.) (Including all subdirectories) and exclude some files, how.gitignore works ( http://git-scm.com/docs/gitignore )

With fnmatch ( https://docs.python.org/2/library/fnmatch.html ) I can "filter" files using a template

ignore_files = ['*.jpg', 'foo/', 'bar/hello*']
matches = []
for root, dirnames, filenames in os.walk('.'):
  for filename in fnmatch.filter(filenames, '*'):
      matches.append(os.path.join(root, filename))

how can I "filter" and get all files that do not match one or more elements of my "ignore_files"?

Thank you
