如何使用python的PID查看Python正在读取或编辑的文件？

import psutil

def find_open_files_by_pid(pid):
    try:
        process = psutil.Process(pid)
        file_handles = process.open_files()
        open_files = [file_obj.path for file_obj in file_handles]
        return open_files
    except psutil.NoSuchProcess:
        return []

def find_open_files_by_python():
    python_processes = [proc for proc in psutil.process_iter(['pid', 'name']) if proc.info['name'] == 'python']
    open_files = []
    for python_proc in python_processes:
        pid = python_proc.info['pid']
        open_files.extend(find_open_files_by_pid(pid))
    return open_files

if __name__ == "__main__":
    open_files = find_open_files_by_python()
    print("Python正在读取或编辑的文件：")
    for file in open_files:
        print(file)
