Python event start from file funcion

from watchdog.observers import Observer
from watchdog.events import FileSystemEventHandler

class WatchPendingHandler(FileSystemEventHandler):
    ''' Run a handler for every file added to the pending dir

    This class also handles what I call a bug in the watchdog module
    which means that you can get more than one call per real event
    in the watched dir tree.
    '''

    def __init__(self):
        super(WatchPendingHandler, self).__init__()
        # wip is used to avoid bug in watchdog which means multiple calls
        # for one real event.
        # For reference: https://github.com/gorakhargosh/watchdog/issues/346
        self.wip = []

    def on_created(self, event):
        path = event.src_path
        if event.is_directory:
            logging.debug('WatchPendingHandler() New dir created in pending dir: {}'.format(path))
            return
        if path in self.wip:
            logging.debug('WatchPendingHandler() Dup created event for %s', path)
            return
        self.wip.append(path)
        logging.debug('WatchPendingHandler() New file created in pending dir: {}'.format(path))
        HandleNewlyCreated(path)

    def on_moved(self, event):
        logging.debug('WatchPendingHandler() %s has been moved', event.src_path)
        with contextlib.suppress(ValueError):
            self.wip.remove(event.src_path)

    def on_deleted(self, event):
        path = event.src_path
        logging.debug('WatchPendingHandler() %s has been deleted', path)
        with contextlib.suppress(ValueError):
            self.wip.remove(path)

observer = Observer()
observer.schedule(WatchPendingHandler(), DIR_PENDING, recursive=True)
observer.start()
logging.info('Watching %s', DIR_PENDING)
try:
    while True:
        time.sleep(1)
except KeyboardInterrupt:
    observer.stop()
observer.join()
