  print "AVERAGE SCORE = %.02f"% (total / count)

score = re.findall("\d.\d\d", line)[0]
This was causing 10.00 to not be added to the total.
I changed to:
score = re.findall("\d+.\d\d", line)[0]
and it works now

Thanks for the script!
I changed it to use subprocess, because os.popen had problems with Windows paths with spaces and made it Pylint compliant to the standard config, except for the global statement.
If you want to merge: https://gist.github.com/PatrickSchiffmann/94b31329fbcef92bead8

pylint can give you a negative score, need to updated score regex for that as well

What about python files that don't have a .py extension?

@surekasri
if module[-3:] == ".py":

can be changed to something like
if module[-3:] in extensions
extension array would contain ".XX" where XX is an extension.

If you need a longer/shorter extensions I would create some regex ;)
