In the JSON world, we can consider terms like encoding/decoding as synonyms to serializing/deserializing. They basically all mean transforming to and back from JSON. In the following example, I'm going to show you how to encode complex numbers:
# json_examples/json_cplx.pyimport jsonclass ComplexEncoder(json.JSONEncoder): def default(self, obj): if isinstance(obj, complex): return { '_meta': '_complex', 'num': [obj.real, obj.imag], } return json.JSONEncoder.default(self, obj)data = { 'an_int': 42, 'a_float': 3.14159265, 'a_complex': 3 + 4j,}json_data = json.dumps(data, cls=ComplexEncoder)print(json_data)def object_hook(obj): try: if obj['_meta'] == '_complex': return complex(*obj['num']) except (KeyError, ...
