    public class Person
    {
        private int age;
        private string name;
        private string sex;
        public int Age
        {
            get { return age; }
            set { age = value; }
        }
        public string Name
        {
            get { return name; }
            set { name = value; }
        }
        public string Sex
        {
            get { return sex; }
            set { sex = value; }
        }
        public virtual void ShowInfo()
        {
            string output = "姓名：" + name + "，性别：" + sex + "，年龄" + age.ToString();
            //调用打印机的类，请自行实现
            //参考这个文章 https://www.cnblogs.com/wendj/p/10728685.html
            //Printer.Print(output);
        }
    }

看你的贴图，这不是python的，推测是c#的，给你个c#代码
