json.loads可以忽略尾随逗号吗? [英] Can json.loads ignore trailing commas?

问题描述

如此StackOverflow问题中所述，则不允许在json中使用任何结尾的逗号.例如，这个

As mentioned in this StackOverflow question, you are not allowed to have any trailing commas in json. For example, this

{
    "key1": "value1",
    "key2": "value2"
}

很好，但这

{
    "key1": "value1",
    "key2": "value2",
}

语法无效.

出于其他StackOverflow问题中提到的原因，使用逗号结尾是合法的(也许鼓励?)在Python代码中.我同时使用Python和JSON，因此我希望能够在两种类型的文件之间保持一致.有没有办法让json.loads忽略尾随逗号?

For reasons mentioned in this other StackOverflow question, using a trailing comma is legal (and perhaps encouraged?) in Python code. I am working with both Python and JSON, so I would love to be able to be consistent across both types of files. Is there a way to have json.loads ignore trailing commas?

推荐答案

您可以使用 jsoncomment包装python的json解析器

JSON Comment允许使用以下命令解析JSON文件或字符串:

JSON Comment allows to parse JSON files or strings with:

• 单行和多行注释
• 多行数据字符串
• 在最后一项之后的对象和数组中尾随逗号

• Single and Multi line comments
• Multi line data strings
• Trailing commas in objects and arrays, after the last item

示例用法:

import json
from jsoncomment import JsonComment

with open(filename) as data_file:    
    parser = JsonComment(json)
    data = parser.load(data_file)
