如何从JSON中删除第一个和最后一个方括号

Question

我将以下JSON存储在Hadoop中，由于JSON中的第一个和最后一个方括号，无法在Hive表中加载它。 Hadoop中存储的JSON文件如下所示

[
  {
    firstname:"kunal",
    lastname:"gupta",
    age:20
  },
  {
    firstname:"Abhishek",
    lastname:"gautam",
    age:20
  },
  {
    firstname:"Neha",
    lastname:"gupta",
    age:20
  }
]

请帮我删除使用Python脚本的第一个和最后一个方括号，以便JSON看起来如下所示： -

{
    firstname:"kunal",
    lastname:"gupta",
    age:20
},
{
    firstname:"Abhishek",
    lastname:"gautam",
    age:20
},
{
    firstname:"Neha",
    lastname:"gupta",
    age:20
}
