Add string to python list -> json object

Question

I have the list below:

rainbow = ['green', 'red', 'blue', 'yellow' ,'orange']

and I would like the output to be a JSON object like so:

{
  "rainbow":[
    {
        "color": "green"
    },
    {
        "color": "red"
    },
    {
        "color": "blue"
    },
    {
        "color": "yellow"
    }
    {
        "color": "orange"
    }
]}

any ideas? I've tried a couple of things and been struggling to find a solution.

import json
import itertools

rainbow = ['green', 'red', 'blue', 'yellow' ,'orange']

d = dict((k,'color') for k in rainbow)

skittles = json.dumps(d)

print skittles

{"blue": "color", "orange": "color", "green": "color", "yellow": "color", "red": "color"}

Maybe you're close to the solution? Post your code.

Your solution creates a flat dictionary with wrong key-value order. You should try something like:

{'rainbow': [{'color': color} for color in rainbow]}

This creates a 'rainbow' key, with a list of dictionaries as its value (created using list comprehension).

You can do this something like that:

import json
json.dumps({"rainbow": [{"color": color} for color in rainbow]})
