watchdog示例：

import sys
import time
import logging
from watchdog.observers import Observer
from watchdog.events import LoggingEventHandler


if __name__ == "__main__":

    # 配置日志
    logging.basicConfig(level=logging.INFO,
                        format='%(asctime)s - %(message)s',
                        datefmt='%Y-%m-%d %H:%M:%S')
    # 需要监控的文件夹路径
    path = sys.argv[1] if len(sys.argv) > 1 else '.'
    # 带有日志输出的文件操作时间
    event_handler = LoggingEventHandler()
    # 创建监控对象
    observer = Observer()
    observer.schedule(event_handler, path, recursive=True)
    observer.start()
    try:
        while True:
            time.sleep(1)
    except KeyboardInterrupt:
        observer.stop()
    observer.join()
