Serialization of those data types is not defined in the JSON standard: https://www.json.org/ so you have to extend the parser/serializers to support them. On 02.11.2018 17:19, Philip Martin wrote:
Is there any reason why date, datetime, and UUID objects automatically serialize to default strings using the csv module, but json.dumps throws an error as a default? i.e.
import csv import json import io from datetime import date
stream = io.StringIO() writer = csv.writer(stream) writer.writerow([date(2018, 11, 2)]) # versus json.dumps(date(2018, 11, 2))
