1、监控指定目录

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):
        now = time.strftime("%Y-%m-%d %H:%M:%S",time.localtime())
        if event.is_directory:
            print(f"{ now } 文件夹由 { event.src_path } 移动至 { event.dest_path }")
        else:
            print(f"{ now } 文件由 { event.src_path } 移动至 { event.dest_path }")

    def on_created(self,event):
        now = time.strftime("%Y-%m-%d %H:%M:%S",time.localtime())
        if event.is_directory:
            print(f"{ now } 文件夹由 { event.src_path } 创建")
        else:
            print(f"{ now } 文件由 { event.src_path } 创建")

    def on_deleted(self,event):
        now = time.strftime("%Y-%m-%d %H:%M:%S",time.localtime())
        if event.is_directory:
            print(f"{ now } 文件夹 { event.src_path } 删除")
        else:
            print(f"{ now } 文件 { event.src_path } 删除")

    def on_modified(self,event):
        now = time.strftime("%Y-%m-%d %H:%M:%S",time.localtime())
        if event.is_directory:
            print(f"{ now } 文件夹 { event.src_path } 修改")
        else:
            print(f"{ now } 文件 { event.src_path } 修改")

if __name__ == "__main__":
    observer = Observer()
    path = r"d:/test/"
    event_handler = FileEventHandler()
    observer.schedule(event_handler,path,True)
    print(f"监控目录 { path }")
    observer.start()
    observer.join()

2、监控指定目录内指定的格式文档

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

class FileEventHandler(FileSystemEventHandler):
    def __init__(self,control):
        FileSystemEventHandler.__init__(self)
        self.control = control


    def on_moved(self,event):
        now = time.strftime("%Y-%m-%d %H:%M:%S",time.localtime())
        if event.src_path.endswith(self.control):
            print(f"{ now } 文件由 { event.src_path } 移动至 { event.dest_path }")

    def on_created(self,event):
        now = time.strftime("%Y-%m-%d %H:%M:%S",time.localtime())
        if event.src_path.endswith(self.control):
            print(f"{ now } 文件由 { event.src_path } 创建")

    def on_deleted(self,event):
        now = time.strftime("%Y-%m-%d %H:%M:%S",time.localtime())
        if event.src_path.endswith(self.control):
            print(f"{ now } 文件 { event.src_path } 删除")

    def on_modified(self,event):
        now = time.strftime("%Y-%m-%d %H:%M:%S",time.localtime())
        if event.src_path.endswith(self.control):
            print(f"{ now } 文件 { event.src_path } 修改")

if __name__ == "__main__":
    observer = Observer()
    path = r"d:/test/"
    event_handler = FileEventHandler('.docx')
    observer.schedule(event_handler,path,True)
    print(f"监控目录 { path }")
    observer.start()
    observer.join()
