通过python写一个程序，监控指定文件夹内文件的增，删，改情况，需要输出删除者，所删除的文件，执行删除操作的程序名等信息

可以使用Python模块watchdog来实现文件夹监控，通过监控事件来判断文件的增删改情况。使用psutil模块获取删除操作的程序名。

下面是一个代码示例，可以根据需要进行修改：

import time
import os
import psutil
from watchdog.observers import Observer
from watchdog.events import FileSystemEventHandler


class MyHandler(FileSystemEventHandler):
    def on_created(self, event):
        print(f"Created: {event.src_path}")

    def on_deleted(self, event):
        filename = os.path.basename(event.src_path)
        print(f"Deleted: {event.src_path}")
        self.show_delete_process(filename)

    def on_modified(self, event):
        print(f"Modified: {event.src_path}")

    def on_moved(self, event):
        print(f"Moved: {event.src_path} to {event.dest_path}")

    def show_delete_process(self, filename):
        for proc in psutil.process_iter(['pid', 'name']):
            try:
                for f in proc.open_files():
                    if os.path.basename(f.path) == filename:
                        print(f"Deleted by {proc.name()}: {filename}")
                        return
            except (psutil.NoSuchProcess, psutil.AccessDenied, psutil.ZombieProcess):
                pass
        print(f"Deleted: {filename} (unknown process)")


if __name__ == "__main__":
    path = "/path/to/watch"
    event_handler = MyHandler()
    observer = Observer()
    observer.schedule(event_handler, path, recursive=True)
    observer.start()
    print(f"Watching {path} for changes...")
    try:
        while True:
            time.sleep(1)
    except KeyboardInterrupt:
        observer.stop()
    observer.join()

运行后，程序会监控指定路径下的文件夹，并输出文件的增删改情况。删除操作会输出删除者和被删除的文件，并通过psutil模块获取删除操作的程序名。
