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 osimport jsonimport 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)
