使用python列表创建动态JSON

Question

这是我在python文件中拥有的json结构。这里，stationList_of_state是一个python列表，它有大约5-10个值，这些值将根据代码动态变化。

        message = {
        "type": "template",
        "payload": {
            "template_type": "generic",
            "elements": 
            [
                {
                    "buttons": [
                            {
                                "title": stationList_of_state[1],
                                "payload": stationList_of_state[1],
                                "type": "postback"
                            }
                        ]
                    }
                ]
            }
        }

我尝试过这样的方法，它显示出错误：

        message = {
            "type": "template",
            "payload": {
                "template_type": "generic",
                "elements": 
                [
                for i in range(len(stationList_of_state)):
                    {
                        "buttons": [
                                {
                                    "title": stationList_of_state[i],
                                    "payload": stationList_of_state[i],
                                    "type": "postback"
                                }
                            ]
                        }
                    ]
                }
            }

有人能对我所做的提出另一种方法吗？

你就快到了

        message = {
            "type": "template",
            "payload": {
                "template_type": "generic",
                "elements": [
                    {
                        "buttons": [
                            {
                                "title": stationList_of_state[i],
                                "payload": stationList_of_state[i],
                                "type": "postback",
                            }
                        ]
                    }
                    for i in range(len(stationList_of_state))
                ],
            },
        }

或者，简化for子句以省略不必要的i变量，

        message = {
            "type": "template",
            "payload": {
                "template_type": "generic",
                "elements": [
                    {
                        "buttons": [
                            {
                                "title": station,
                                "payload": station,
                                "type": "postback",
                            }
                        ]
                    }
                    for station in stationList_of_state
                ],
            },
        }
