How to extend json.JSONEncoder class? I want to encode other Python data types to JSON.

If you encode your own data types to JSON strings,
you need to extend the json.JSONEncoder class and override the default()
function.
The following Python example shows you how to extend json.JSONEncoder class to encode "complex" data type into JSON format:
C:\fyicenter>type MyJSONEncoder.py # MyJSONEncoder.py # Copyright (c) FYIcenter.com import json class MyJSONEncoder(json.JSONEncoder): def default(self, obj): if isinstance(obj, complex): return {'r': obj.real, 'i': obj.imag} return json.JSONEncoder.default(self, obj) encoder = MyJSONEncoder(indent=4) i = 2 f = 2.1 c = 2 + 1j o = {'int': i, 'float': f, 'complex': c} j = encoder.encode(o) print(j) C:\fyicenter>python MyJSONEncoder.py { "int": 2, "float": 2.1, "complex": { "r": 2.0, "i": 1.0 } }
