Dealing with datetime objects when dumping JSON

json_output.py

import json
import datetime


class DTEncoder(json.JSONEncoder):

    def default(self, obj):
        if isinstance(obj, datetime.datetime):
            return obj.isoformat()

        return json.JSONEncoder.default(self, obj)


# assumes data is a dictionary
# e.g. data = ig_data.to_dict()
def json_output(data):
    return json.dumps(data, cls=DTEncoder)
