JSON如何序列化对象并在排除函数的同时包含@property属性？

import json

class CustomEncoder(json.JSONEncoder):
    def default(self, obj):
        if hasattr(obj, '__dict__'):
            data = {}
            for key, value in obj.__dict__.items():
                if not callable(value):
                    data[key] = value
            return data
        return super().default(obj)

class MyClass:
    def __init__(self, name, age):
        self.name = name
        self.age = age

    @property
    def info(self):
        return f"Name: {self.name}, Age: {self.age}"

obj = MyClass("John", 25)
json_str = json.dumps(obj, cls=CustomEncoder)
print(json_str)

{"name": "John", "age": 25}
