在Python中使用json.load时，JSON文件转换为字符串

Question

I have a valid JSON file but when i am using json.load(), it gets converted to string instead of Python dictionary.

My JSON string:

{
  "colors": [
    {
      "color": "black",
      "category": "hue",
      "type": "primary",
      "code": {
        "rgba": [255,255,255,1],
        "hex": "#000"
      }
    },
    {
      "color": "white",
      "category": "value",
      "code": {
        "rgba": [0,0,0,1],
        "hex": "#FFF"
      }
    },
    {
      "color": "red",
      "category": "hue",
      "type": "primary",
      "code": {
        "rgba": [255,0,0,1],
        "hex": "#FF0"
      }
    },
    {
      "color": "blue",
      "category": "hue",
      "type": "primary",
      "code": {
        "rgba": [0,0,255,1],
        "hex": "#00F"
      }
    },
    {
      "color": "yellow",
      "category": "hue",
      "type": "primary",
      "code": {
        "rgba": [255,255,0,1],
        "hex": "#FF0"
      }
    },
    {
      "color": "green",
      "category": "hue",
      "type": "secondary",
      "code": {
        "rgba": [0,255,0,1],
        "hex": "#0F0"
      }
    }
  ]
}

It is named as color.json

My Python code is:

import json
with open("color.json") as f:
    data=json.load(f)
print(type(data))

It shows output as class 'str'. why is it not being converted to dictionary?

Answer 1

I have extended your code as below with your provided json file

import json
with open("color.json") as f:
    data=json.load(f)
print(type(data))

listofkeys=[keys for keys in data.keys()]
print(listofkeys)

color_keys=[keys2 for keys2 in data["colors"][0].keys()]
print(color_keys)

And Output is as below

<class 'dict'>
['colors']
['category', 'color', 'code', 'type']

First thing is it is returning dict type only. And it is having only one key colors as we have printed out.

And Second thing is this colors key is having list of dictionaries as its value which are as well printed in our code. category color code type are four dictionaries

And you can further explore these dictionaries.

and the above mentioned code is working in both python2 and 3 versions. Check again.
