python watchdog monitoring file for changes -

folks, have need watch log file changes. after looking through stackoverflow questions, see people recommending 'watchdog'. i'm trying test, , not sure add code when files change:

#!/usr/bin/python import time watchdog.observers import observer watchdog.events import loggingeventhandler  if __name__ == "__main__": event_handler = loggingeventhandler() observer = observer() observer.schedule(event_handler, path='.', recursive=false) observer.start() try:     while true:       time.sleep(1)     else:       print "got it" except keyboardinterrupt:     observer.stop() observer.join() 

where add "got it", in while loop if files have been added/changed?

thanks!

instead of loggingeventhandler define handler:

#!/usr/bin/python import time watchdog.observers import observer watchdog.events import filesystemeventhandler   class myhandler(filesystemeventhandler):     def on_modified(self, event):         print "got it!"   if __name__ == "__main__":     event_handler = myhandler()     observer = observer()     observer.schedule(event_handler, path='.', recursive=false)     observer.start()      try:         while true:             time.sleep(1)     except keyboardinterrupt:         observer.stop()     observer.join() 

on_modified called when file or directory modified.
