如何使用 Python 代码修改 JSON 文件中的字段并复制文件夹中的文件到新路径？

import os import json import shutil  # 获取 json 文件的路径 def get_json_data(old_json_path):     json_file_paths = []     for root, dirs, files in os.walk(old_json_path):         for file_name in files:             if file_name.endswith('.json'):                 old_json_file_path = os.path.join(root, file_name)                 json_file_paths.append(old_json_file_path)     return json_file_paths  # 获取文件夹的路径 def get_dir_name(dir_name):     dir_names = []     for root, dirs, files in os.walk(dir_name):         for dir in dirs:             dirpath = os.path.join(root, dir)             dir_names.append(dirpath)     return dir_names  # 读取 json 文件并更新字段 def read_json(filepath):     with open(filepath, 'r', encoding='utf-8') as f:         json_data = f.read()         if json_data:             json_data_dict = eval(json_data)             json_data_dict.update({"filename": filepath.split('\')[-2].replace('.dav', '.avi')})     return json_data_dict  # 写入 json 文件 def write_json(filepath, newdata):     with open(filepath, 'w', encoding='utf-8') as r:         json.dump(newdata, r, indent=4, ensure_ascii=false)  # 复制 json 文件和其他文件到新路径 def copy_files(old_path, new_path):     dir_names = get_dir_name(old_path)     for dir in dir_names:         json_file_list = get_json_data(dir)         for json_file in json_file_list:             dir_name = dir.split('\')[-1].replace('.dav', '.avi')             new_dir_name = os.path.join(new_path, dir_name)             if not os.path.exists(new_dir_name):                 os.mkdir(new_dir_name)             shutil.copy(json_file, new_dir_name)             newdata = read_json(new_dir_name + '\' + os.path.basename(json_file))             write_json(new_dir_name + '\' + os.path.basename(json_file), newdata)         other_files = []         for root, dirs, files in os.walk(old_path):             for file_name in files:                 if file_name.endswith('.jpg') or file_name.endswith('.avi'):                     other_files.append(os.path.join(old_path, file_name))         for file in other_files:             shutil.copy(file, new_path)  # 主函数 if __name__ == "__main__":     old_path = r'd:ss'     new_path = r'd:json'     copy_files(old_path, new_path)

import os import json  file_path = r'F:scode_pjpj_test	est_data
.json'  with open(file_path) as f:     data = f.read()     if data:         b = eval(data)
