如何修改代码避免照片和视频文件被复制到同一个文件夹？

def get_json_data(old_json_path):    result = []    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)                result.append(old_json_file_path)            elif file_name.endswith('.jpg') or file_name.endswith('.avi'):                # 将照片和视频文件路径加入列表                result.append(os.path.join(root, file_name))    return result

file_path = r'F:scode_pjpj_test	est_data.json'with open(file_path) as f:    data = f.read()    # 判断data是否为空字符串    if not data:        print("EOF error: Empty file.")    else:        # 将data转换为字典        b = eval(data)
