A demo in the official documentation:

>>> Import json>>> class Complexencoder (JSON. Jsonencoder):     ... def default (self, obj): ...         If Isinstance (obj, complex): ...             return [Obj.real, Obj.imag]         ... Return JSON. Jsonencoder.default (self, obj) ...>>> dumps (2 + 1j, Cls=complexencoder) ' [2.0, 1.0] ' >>> Complexencoder (). Encode (2 + 1j) ' [2.0, 1.0] ' >>> list (Complexencoder (). Iterencode (2 + 1j)) [' [', ' 2.0 ', ', ', ' 1.0 ‘, ‘]‘]

Then simply extend a jsonencoder out to format the time

Class Cjsonencoder (JSON. Jsonencoder):    def default (self, obj):        if Isinstance (obj, datetime):            return Obj.strftime ('%y-%m-%d%h:%m: %s ')        elif isinstance (obj, date):            return obj.strftime ('%y-%m-%d ')        else:            return JSON. Jsonencoder.default (self, obj)

When using, simply add a CLS parameter to the Json.dumps:

Json.dumps (DataList, Cls=cjsonencoder)

If you do not want to define a class, you can format it directly after the date or DateTime object we get, using the Strftime method.
