我需要使用JSON将嵌套Python字典写入文本文件，文本文件将被视为C++字典（使用OpenFo沫）。

Question

我使用json dump编写了文本文件，然后使用python读写循环删除了双引号和冒号，但是我仍然必须为每个键值添加分号，我不知道该怎么做。有谁能建议最好的方法是什么

这就是字典（python）的样子

fvSolution={"FoamFile":{
                "version"  :    "2.0",
                "class"    : "dictionary",
            },
             "solvers":{
                "p" : {
                    "solver" :"PCG",
                    "preconditioner" :"DIC",
                    "tolerance" :1e-06,
                    "relTol" :0.01
                    }
                }
            }

这就是文本文件的样子，我需要将我的字典转换成这个

FoamFile
{
    version 2.0;
    class   dictionary;
    format  ascii;
}
solvers
{
    p
    {
        solver           PCG;
        preconditioner   DIC;
        tolerance        1e-06;
        relTol           0.01
    }
}

这是我的密码：
