如何避免在mjson.tool中进行实数转换 [英] How to avoid real numbers conversions in mjson.tool

问题描述

我发现mjson.tool使用科学计数法转换实数，例如:

I have discovered that mjson.tool converts real number using scientific notation, e.g:

$ echo '{"k":0.000000581}' | python -mjson.tool
{
    "k": 5.81e-07
}

但是，我想避免这种转换，因此前者将打印为:

However, I would like to avoid this conversion, so the former get printed as:

{
    "k": 0.000000581
}

可以通过这种方式使用mjson.tool吗?

It is possible to use mjson.tool in such way, please?

推荐答案

据我所见，mjson模块只是将输入转换为json，然后使用缩进和排序键将其转换回字符串.

From what I see, mjson module just convert the input to json and back to string with indentation and sorted keys.

这可以通过以下方式完成:

This can be done with:

>>> json.dumps(json.loads('{"k":0.000000581}', indent=2, sort_keys=True))
'{"k": 5.81e-07}'

编辑:任何仅重新格式化但不尝试解析/广播类型的工具都可以使用.

Edit: Any tools that only reformat and does not try to parse/cast types will work.

我尝试了 yajl-tools :

user$ sudo apt-get install yajl-tools
user$ echo '{"a": 0.0000000000000001337}' | json_pp 
{
   "a" : 1.337e-16
}
user$ echo '{"a": 0.0000000000000001337}' | json_reformat
{
    "a": 0.0000000000000001337
}
