In Python, you can access JSON properties using classes. First, you need to load the JSON data into a dictionary object in Python, and then you can use that dictionary object as a property of the class. Below is an example code:

import json

# JSON数据
json_data = '{"name": "Alice", "age": 30, "city": "New York"}'

# 将JSON数据加载到Python字典对象中
data = json.loads(json_data)

# 定义一个类
class Person:
    def __init__(self, data):
        self.name = data['name']
        self.age = data['age']
        self.city = data['city']

# 创建一个实例并访问JSON属性
person = Person(data)
print(person.name)
print(person.age)
print(person.city)

In this example, we start by loading JSON data into a Python dictionary object called ‘data’. Then we define a Person class with properties like name, age, and city, with values corresponding to those in the ‘data’ dictionary. Finally, we create an instance of the Person class and access the JSON properties.
