将Python字典转换为没有字符串键的JSON对象

Question

I had created a kaggle Notebook kernel - Please Checkout it - with countries of the world data source, in order to obtain a list of JSON objects that handles each country and its respective population, because I want to use a textual copy of it in JavaScript.

I used the following code:

data = []

import csv
import json
import os
for dirname, _, filenames in os.walk('/kaggle/input'):
    for filename in filenames:
        file_name = os.path.join(dirname, filename)
        print(file_name)
        print('Done!')

# Any results you write to the current directory are saved as output.
# LOOK AT THE FOLLOWING Method:
def load_tokens(tokens_file):
    try:
        with open(tokens_file) as csvDataFile:
            csvReader = csv.reader(csvDataFile)

            for i,row in enumerate(csvReader):

                data.insert(i,json.loads(json.dumps({'country':row[0].strip(), 'population':row[2].strip()})))

The active code here is load_tokens() method. What I have ended with is an output print(data) like the following:

[{'country': 'Country', 'population': 'Population'}, {'country': 'Afghanistan', 'population': '31056997'}, {'country': 'Albania', 'population': '3581655'}, {'country': 'Algeria', 'population': '32930091'},...]

My problem here is the dictionary keys. ie 'country' and 'population' I don't want them to be strings. I need them to be JSON object's keys like found in JavaScript:

[{country: 'Country', population: 'Population'},{country: 'Afghanistan', population: '31056997'},...

Answer 1

Well formatted JSON should use strings as keys, like this: {"country": "Country"}

The fact that you can declare objects using {country: "Country"} in js is just a convenience shortcut. Declaring with quotes works the same, or sometimes better (your key can use +/- and other chars).

Don't convert from JSON back to python objects (using json.loads()), though. Python objects are not JSON objects, and even in how they are displayed there are subtle differences.
