使用python将JSON数据转换为字符串数据

import json

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

# 将Python对象转换为JSON字符串
json_string = json.dumps(data)

print(json_string)

{"name": "Alice", "age": 30, "city": "New York"}

import json

class MyClass:
    def __init__(self, value):
        self.value = value

def serialize(obj):
    if isinstance(obj, MyClass):
        return {"value": obj.value}
    raise TypeError(f"Object of type {obj.__class__.__name__} is not JSON serializable")

data = {
    "name": "Alice",
    "age": 30,
    "city": "New York",
    "extra": MyClass("some value")
}

json_string = json.dumps(data, default=serialize)
print(json_string)
