监视文件目录更改多行返回

Question

在运行此代码时，Python返回多个条目。不知道为什么它不能运行一次。

我尝试更改睡眠时间，但是不确定这里发生了什么。

import time
from watchdog.observers import Observer
from watchdog.events import FileSystemEventHandler
from subprocess import call

class Watcher:
    DIRECTORY_TO_WATCH = r"C:\Users\tgaluska\File"

    def __init__(self):
        self.observer = Observer()

    def run(self):
        event_handler = Handler()
        self.observer.schedule(event_handler, self.DIRECTORY_TO_WATCH, recursive=True)
        self.observer.start()
        try:
            while True:
                time.sleep(5)
        except:
            self.observer.stop()
            print ("Error")
        self.observer.join()

class Handler(FileSystemEventHandler):
     def on_any_event(self,event):
        if event.is_directory:
            return None
        elif event.event_type == 'modified':
            print ("Received modified event - %s." % event.src_path)

if __name__ == '__main__':
        w = Watcher()
        w.run()

Received modified event - C:\Users\tg\File\Superstore.xls.
Received modified event - C:\Users\tg\File\Superstore.xls.
