我有一个多GB的JSON文件.该文件由JSON对象组成,每个对象不超过几千个字符,但记录之间没有换行符.

使用Python 3和json模块,我如何一次从文件读入一个JSON对象到内存？

数据位于纯文本文件中.这是一个类似记录的例子.实际记录包含许多嵌套字典和列表.

以可读格式记录:

{
    "results": {
      "__metadata": {
        "type": "DataServiceProviderDemo.Address"
      },
      "Street": "NE 228th",
      "City": "Sammamish",
      "State": "WA",
      "ZipCode": "98074",
      "Country": "USA"
    }
  }
}

实际格式.新记录一个接一个地开始,没有任何中断.

{"results": { "__metadata": {"type": "DataServiceProviderDemo.Address"},"Street": "NE 228th","City": "Sammamish","State": "WA","ZipCode": "98074","Country": "USA" } } }{"results": { "__metadata": {"type": "DataServiceProviderDemo.Address"},"Street": "NE 228th","City": "Sammamish","State": "WA","ZipCode": "98074","Country": "USA" } } }{"results": { "__metadata": {"type": "DataServiceProviderDemo.Address"},"Street": "NE 228th","City": "Sammamish","State": "WA","ZipCode": "98074","Country": "USA" } } }
