                    path = (base + '/'+ file)
                    c = read_line_count(path)
                    print ".%s : %d" % (path[len(here):], c)
                    line_count += c
            except:
                pass
    print 'File count : %d' % file_count
    print 'Line count : %d' % line_count

Copy and save the script as analytics.py and modify the exts list to include all the file extensions in your project, and put this script in your source code folder, then run:

python analytics.py
