python 自定义类转字符串

要将Python自定义类转换为字符串，可以使用JSON模块的dumps()方法。首先，需要在自定义类中实现一个to_dict()方法，该方法将自定义类的属性转换为字典。然后，使用dumps()方法将字典转换为JSON字符串。

以下是将自定义类Person转换为字符串的示例代码：

import json

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

    def to_dict(self):
        return {
            'name': self.name,
            'age': self.age
        }

person = Person('John', 25)
json_string = json.dumps(person.to_dict())

print(json_string)

这样，person对象就会被转换为JSON字符串，并且可以在需要的地方使用。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
