在json中合并重复的键

Question

我有一个像这样的json：

{
  "course1": [
    {
      "courseName": "test",
      "section": "123",
      "academicHours": "3",
      "day1": "1",
      "room1": "0145 03 1 B 015"
    }
  ],
  "course2": [
    {
      "courseName": "test",
      "section": "456",
      "academicHours": "3",
      "day1": "1",
      "room1": "0145 03 1 B 015"
    }
  ],
  "course2": [
    {
      "courseName": "test",
      "section": "789",
      "academicHours": "3",
      "day1": "1",
      "room1": "0145 03 1 B 015"
    }
  ],
  "course2": [
    {
      "courseName": "test",
      "section": "1011",
      "academicHours": "3",
      "day1": "1",
      "room1": "0145 03 1 B 015"
    }
  ],
  "course3": [
    {
      "courseName": "test",
      "section": "1213",
      "academicHours": "3",
      "day1": "1",
      "room1": "0145 03 1 B 015"
    }
  ],
  "course3": [
    {
      "courseName": "test",
      "section": "1415",
      "academicHours": "3",
      "day1": "1",
      "room1": "0145 03 1 B 015"
    }
  ]
}

我希望组合任何块/对象/列表(我不知道它叫什么)，使它们具有相同的键值。就像这样：

{
  "course1": [
    {
      "courseName": "test",
      "section": "123",
      "academicHours": "3",
      "day1": "1",
      "room1": "0145 03 1 B 015"
    }
  ],
  "course2": [
    {
      "courseName": "test",
      "section": "456",
      "academicHours": "3",
      "day1": "1",
      "room1": "0145 03 1 B 015"
    },
    {
      "courseName": "test",
      "section": "789",
      "academicHours": "3",
      "day1": "1",
      "room1": "0145 03 1 B 015"
    },
    {
      "courseName": "test",
      "section": "1011",
      "academicHours": "3",
      "day1": "1",
      "room1": "0145 03 1 B 015"
    }
  ],
  "course3": [
    {
      "courseName": "test",
      "section": "1213",
      "academicHours": "3",
      "day1": "1",
      "room1": "0145 03 1 B 015"
    },
    {
      "courseName": "test",
      "section": "1415",
      "academicHours": "3",
      "day1": "1",
      "room1": "0145 03 1 B 015"
    }
  ]
}

我如何使用python中的正则表达式来完成这个任务？或者任何正则表达式查询？

此外，我尝试使用json.dumps()并从那里开始工作，但由于某种原因，当我将它与任何包含阿拉伯字符的json一起使用时，它就会抓狂，把整件事情搞砸。所以我很不幸地被正则表达式困住了。

谢谢你的帮助:)

stdlib json提供了一个钩子，允许使用重复键解码对象。这个简单的“扩展”钩子应该适用于示例数据：

def myhook(pairs):
    d = {}
    for k, v in pairs:
        if k not in d:
          d[k] = v
        else:
          d[k] += v
    return d

mydata = json.loads(bad_json, object_pairs_hook=myhook)

虽然JSON规范中没有任何东西不允许重复的键，但首先应该避免它：

1.1。本文件中使用的关键词“必须”、“不得”、“要求”、“应”、“不应”、“不应”、“建议”、“可”和“可选”应解释为RFC2119所述。

..。

1. 对象

对象结构表示为围绕零或多个名称/值对(或多个成员)的一对花括号。名字是字符串。在每个名称之后加上一个冒号，将名称与值分隔开来。一个逗号将值与下面的名称分隔开来。对象中的名称应该是唯一的。
