"data":{ "12321":[ { "code":"1213", "codename":"13213" } ], "12321.1213":[ { "code":"1321", "codename":"1321" } ], "12@aa米":[ { "code":"12@", "codename":"ss米" } ], "12@aa米.12@":[ { "code":"", "codename":"" } ],怎样获取data里面所有的code和codename，不用根据data[12321]来获取响应的数据

您可以使用循环遍历来获取data中所有的code和codename。以下是一个示例代码：

data = {
    "12321": [
        {
            "code": "1213",
            "codename": "13213"
        }
    ],
    "12321.1213": [
        {
            "code": "1321",
            "codename": "1321"
        }
    ],
    "12@aa米": [
        {
            "code": "12@",
            "codename": "ss米"
        }
    ],
    "12@aa米.12@": [
        {
            "code": "",
            "codename": ""
        }
    ]
}

all_codes = []
all_codenames = []

for key in data:
    for item in data[key]:
        code = item['code']
        codename = item['codename']
        all_codes.append(code)
        all_codenames.append(codename)

print(all_codes)
print(all_codenames)

这样，您将获得所有的code和codename，存储在`all_codes`和`all_codenames`列表中。
