Simple way to jsonify an simple array as key: value

Question

Is there a simple way in python/flask to jsonify an array of strings as a key/value pair?

So far I understood, that I can jsonify with following code:

fruits = ["apple", "pear", "melon"]
return jsonify(fruits)

which returns

["apple", "pear", "melon"]

Now, what is the simplest way to get this as a key/value like

{
    "fruits": ["apple", "pear", "melon"]
}

well. my question would be rather: Do I have to make a dictionary first then jsonify, or is there simple predefined function which makes this in a one-liner — kxell2001, Apr 13 '20 at 13:01

Is this what you are looking for?

let fruits = ["apple", "pear", "melon"]
let fruitsObj = { fruits }
let json = JSON.stringify(fruitsObj)

Look at this answer for an explanation as to why this isn't simple to implement.

Instead, try:

import json
obj_dict = {"fruits": ["apple", "pear", "melon"]}
print(json.dumps(obj_dict))
