公司项目最近写了个监听文件夹工具，本身不是写python的，想到用while 1写循环写，跑着跑着卡，后台又用定时任务跑，效果不太理想 最后发现 watchdog 包  主要可以监听 文件内的创建  更改 删除等，随时监听。

网上watchdog  demo  ，配合根据这个修改

pip install  watchdog

from watchdog.observers import Observer
from watchdog.events import *
import time


class FileEventHandler(FileSystemEventHandler):
    def __init__(self):
        FileSystemEventHandler.__init__(self)

    def on_moved(self, event):
        if event.is_directory:
            print("directory moved from {0} to {1}".format(event.src_path, event.dest_path))
        else:
            print("file moved from {0} to {1}".format(event.src_path, event.dest_path))

    def on_created(self, event):
        if event.is_directory:
            print("directory created:{0}".format(event.src_path))
        else:
            print("file created:{0}".format(event.src_path))

    def on_deleted(self, event):
        if event.is_directory:
            print("directory deleted:{0}".format(event.src_path))
        else:
            print("file deleted:{0}".format(event.src_path))

    def on_modified(self, event):
        if event.is_directory:
            print("directory modified:{0}".format(event.src_path))
        else:
            print("file modified:{0}".format(event.src_path))


if __name__ == "__main__":
    observer = Observer()
    event_handler = FileEventHandler()
    observer.schedule(event_handler, r"C:\Users\wyq\Desktop\1", True)
    observer.start()
    try:
        while True:
            time.sleep(1)
    except KeyboardInterrupt:
        observer.stop()
    observer.join()
