创建新文件时运行python脚本

我认为看守者库是在这里使用的更好的东西，就像火葬者所提到的那样。我已使用它如下监视新文件的文件夹：

import time from watchdog.observers import Observerfrom watchdog.events import FileSystemEventHandlerclass ExampleHandler(FileSystemEventHandler):    def on_created(self, event): # when file is created        # do something, eg. call your function to process the image        print "Got event for file %s" % event.src_pathobserver = Observer()event_handler = ExampleHandler() # create event handler# set observer to use created handler in directoryobserver.schedule(event_handler, path='/folder/to/watch')observer.start()# sleep until keyboard interrupt, then stop + rejoin the observertry:    while True:        time.sleep(1)except KeyboardInterrupt:    observer.stop()observer.join()
