如何跳过使用构建器模式设置属性

class Person:
    def __init__(self):
        self.name = ""
        self.age = 0
        self.gender = ""

    def set_name(self, name):
        self.name = name

    def set_age(self, age):
        self.age = age

    def set_gender(self, gender):
        self.gender = gender

    def __str__(self):
        return f"Name: {self.name}, Age: {self.age}, Gender: {self.gender}"


# 创建对象实例
person = Person()

# 直接设置属性值
person.name = "John"
person.age = 30
person.gender = "Male"

print(person)  # 输出对象属性值
