Python 如何编辑或访问非标准JSON文件'；s值是否正确

我有一个非标准格式的JSON文件，如下所示：

{
    "color": "black",
    "category": "hue",
    "type": "primary"
}
{
    "color": "white",
    "category": "value",
    "type": "idk"
}
{
    "color": "red",
    "category": "hue",
    "type": "primary"
}

[
    {
        "color": "black",
        "category": "hue",
        "type": "primary"
    },
    {
        "color": "white",
        "category": "value",
        "type": "idk"
    },
    {
        "color": "red",
        "category": "hue",
        "type": "primary"
    },
]

但它有超过10000个条目以这种方式格式化。我必须访问每个单独部分的颜色和类型，并为每个部分创建一个字符串，表示“type color”，如“primary black”

我想用Python编辑文件，使其看起来像这样：

{
    "color": "black",
    "category": "hue",
    "type": "primary"
}
{
    "color": "white",
    "category": "value",
    "type": "idk"
}
{
    "color": "red",
    "category": "hue",
    "type": "primary"
}

[
    {
        "color": "black",
        "category": "hue",
        "type": "primary"
    },
    {
        "color": "white",
        "category": "value",
        "type": "idk"
    },
    {
        "color": "red",
        "category": "hue",
        "type": "primary"
    },
]

因此，我可以使用[]访问值，并对所有值使用for循环。我该怎么做？有没有比编辑json文件更好的方法呢？

文件是json还是不是json，而您给出的示例文件不是。将其称为“非标准JSON”是不准确和令人困惑的

也就是说，下面是我将如何使用Python将该文件转换为真正的JSON的概要：

Open a new file for writing.
Write "[" to the output file.
Open your existing file for reading.
For each line in the file:
    Write that line to the output file.
    If that line is "}", but it is not the last line, also write a comma.
Write ] to the output file.

您可以使用

str.format

In [341]: with open('f.json', 'r') as f:
     ...:     string = f.read()
     ...:

In [342]: string
Out[342]: '{\n    "color": "black",\n    "category": "hue",\n    "type": "primary"\n}\n{\n    "color": "white",\n    "category": "value",\n    "type": "idk"\n}\n{\n    "color": "red",\n    "category": "hue",\n    "type": "primary"\n}\n'

In [343]: string = string.replace('}','},') # Must split each '{}' with a comma

In [344]: string
Out[344]: '{\n    "color": "black",\n    "category": "hue",\n    "type": "primary"\n},\n{\n    "color": "white",\n    "category": "value",\n    "type": "idk"\n},\n{\n    "color": "red",\n    "category": "hue",\n    "type": "primary"\n},\n'

In [345]: string = string[:-2] # Get rid of the trailing comma

In [346]: string
Out[346]: '{\n    "color": "black",\n    "category": "hue",\n    "type": "primary"\n},\n{\n    "color": "white",\n    "category": "value",\n    "type": "idk"\n},\n{\n    "color": "red",\n    "category": "hue",\n    "type": "primary"\n}'

In [347]: json.loads('[{0}]'.format(string))
Out[347]:
[{'color': 'black', 'category': 'hue', 'type': 'primary'},
 {'color': 'white', 'category': 'value', 'type': 'idk'},
 {'color': 'red', 'category': 'hue', 'type': 'primary'}]

你真的不需要Python

sed'1s/^/[/；$！/}/}，/；$s/$/]/'file>file.json

上述代码实际上修复了伪代码的错误；如果这是最后一行，请不要加逗号。Soo还@tripleee感谢您的错误发现！我已经编辑了我的答案。谢谢，我以前从未使用过JSON文件，提供该文件的人说它是JSON“_(ツ)_/''但我应该知道。@tripleee您提供的链接在每行中添加了一个逗号，因此它与我的代码不兼容。如果有办法编辑它，只在以}结尾的行中添加逗号，那将非常有用
