使用python从JSON文件中读取数组

I have this JSON file:

我有这个JSON文件：

[
{
id: "29",
name: "abc",
email: "def@school.edu",
data: "2016-05-03"
},
{
id: "17",
name: "ghi",
email: "jkl@school.edu",
data: "2016-05-12"
},
{
id: "12",
name: "qwe",
email: "cde@school.edu",
data: "2016-04-11"
}
]

I wrote this script:

我写了这个脚本：

with open('C:/Users/L30607/Desktop/FYP/FourthMay-AllStudents-*.json') as json_data:
    d = json.load(json_data)
    json_data.close()
    pprint(d)

How do I parse the file and extract the array?

如何解析文件并解压缩数组？

I want to get:

我想得到：

d = [{id: "29",name: "abc",email: "def@school.edu",data: "2016-05-03"},{id: "17",name: "ghi",email: "jkl@school.edu",data: "2016-05-12"},{id: "12",name: "qwe",email: "cde@school.edu",data: "2016-04-11"}]

Your JSON is not formatted properly. I put validated it in https://jsonformatter.curiousconcept.com/ and it shows that your keys are not wrapped in quotes. This is what it should be:

您的JSON格式不正确。我把它验证在https://jsonformatter.curiousconcept.com/中，它表明你的密钥没有用引号括起来。它应该是这样的：

[  
   {  
      "id":"29",
      "name":"abc",
      "email":"def@school.edu",
      "data":"2016-05-03"
   },
   {  
      "id":"17",
      "name":"ghi",
      "email":"jkl@school.edu",
      "data":"2016-05-12"
   },
   {  
      "id":"12",
      "name":"qwe",
      "email":"cde@school.edu",
      "data":"2016-04-11"
   }
]

I re-ran your code and it worked well.

我重新运行了你的代码，它运行良好。

Your json should be like :

你的json应该是这样的：

[{
    "id": "29",
    "name": "abc",
    "email": "def@school.edu",
    "data": "2016-05-03"
}, {
    "id": "17",
    "name": "ghi",
    "email": "jkl@school.edu",
    "data": "2016-05-12"
}, {
    "id": "12",
    "name": "qwe",
    "email": "cde@school.edu",
    "data": "2016-04-11"
}]

String should be inside quotes. Then only it becomes as valid JSON. You can validate your JSON : Validate JSON

字符串应该在引号内。然后只有它变成有效的JSON。您可以验证您的JSON：验证JSON

#3

Always validate your json from http://jsonlint.com/ if you get any errors. In your case you are not giving Keys as string.

如果您遇到任何错误，请始终从http://jsonlint.com/验证您的json。在您的情况下，您没有将Keys作为字符串。

This is the error:

这是错误：
