    = response_dict['API.CustomizedApi']['itemlist']['auctions'] 如果想要获取多页数据,可以在上述的代码中加入一个循环,实现代码如下: for ('(')[1].split(')')[0] response_dict = json.loads(response) # 商品信息 response_auctions_info = response_dict['API.CustomizedApi']['itemlist']['auctions'] 数据存储 我们以CSV文件的格式存储数据,我们来定义一个函数,传入参数 分别为 responseauctionsinfo数据集合信息, file_name保存的文件名: def get_auctions_info(response_auctions_info,file_name): : # 判断是否数据已经记录 if str(i['raw_title']) not in auctions_distinct:
