用Python规范JSON

Question

请提示我，如何使用Python规范这个JSON文件？

这个问题与previous有关。

当前的JSON包含：

{
    "total_stats": [
        {
            "domain": "domain.com",
            "uptime": "100"
        },
        {
            "domain": "domain.com",
            "threats": "345.01111783804436"
        }
    ]
}

可取的

{
    "total_stats": [
        {
            "domain": "domain.com",
            "uptime": "100",
            "threats": "345.01111783804436"
        }
    ]
}

Answer 1

如果要根据可以使用的"domain"键合并字典(注意:如果字典有公用键，则将使用最后一个字典值)：

dct = {
    "total_stats": [
        {"domain": "domain.com", "uptime": "100"},
        {"domain": "domain.com", "threats": "345.01111783804436"},
    ]
}


out = {}
for d in dct["total_stats"]:
    out.setdefault(d["domain"], {}).update(d)

dct["total_stats"] = list(out.values())
print(dct)

指纹：

{
    "total_stats": [
        {
            "domain": "domain.com",
            "uptime": "100",
            "threats": "345.01111783804436",
        }
    ]
}
