如何通过Python格式化JSON？

Question

我有一个非常基本的问题，我无法弄清楚。试图将对象数据写入JSON文件时，我一直在获得“ Expect.json的终点”。我想知道如何解决这个问题？我通过写循环来做到这一点。不确定我如何格式化。

这是所讨论的代码

with open("data.json", "w") as outfile:
    for x,y in structures.infrastructures.items():
        outfile.write(Sector(x, y["Depended on by"],y["Depends on"], y["Sub sections"]).toJson())

输出

{
    "name": "Chemical",
    "depended_on": [
        "Critical Manufacturing",
        "Nuclear Reactors, Waste, and Material Management",
        "Commercial",
        "Healthcare and Public Health",
        "Food and Agriculture",
        "Energy"
    ],
    "depends_on": [
        "Emergency Services",
        "Energy",
        "Food and Agriculture",
        "Healthcare and Public Health",
        "Information Technology",
        "Nuclear Reactors, Waste, and Material Management",
        "Transportation Systems",
        "Water"
    ],
    "sub_sections": [
        "Chemical Plants",
        "Chemical Refineries",
        "Labs"
    ],
    "Status": 0,
    "Strain": 0
}{                                  -> this is where the error is
    "name": "Commercial",
    "depended_on": [
    ....
    ....
    etc

，这是我的tojson方法的

    def toJson(self):
        return json.dumps(self, default=lambda o: o.__dict__, indent=4)

：但是，是的，在以JSON格式编写对象数据的地方我该如何实现它？

Answer 1

有效的JSON文件只能包含一个对象。将您的数据收集到列表中，然后用一个调用编写，或用您的代码模拟格式。

Answer 2

您必须使用功能来解析.json

我希望这会有所帮助
