Python实现Json文件转为点表示法(Dot-Notation)

将Json转换为点表示法有很多用途，本文基于Python实现一个简单demo来转换。

{

    "vehicle": {

        "car": {

            "bmw": true,

            "audi": 1,

            "ford": "also good"

        },

        "truck": {

            "all": "cool"

        }

    }

}

转为：

$.vehicle.car.ford : also good

$.vehicle.car.bmw : True

$.vehicle.car.audi : 1

$.vehicle.truck.all : cool

代码：

#! /usr/bin/env python

import json

import pyperclip



def getKeys(val, old="$"):

    if isinstance(val, dict):

        for k in val.keys():

            getKeys(val[k], old + "." + str(k))

    elif isinstance(val, list):

        for i,k in enumerate(val):

            getKeys(k, old + "." + str(i))

    else:

        print("{} : {}".format(old,str(val)))



data = json.loads(pyperclip.paste())

getKeys(data)
