#1. 弱的私有方法和属性在开头只有一个下划线。
#这表示它们是私有的，不应该被外部代码所使用。但它只是一个约定，并没有阻止外部代码访问它们。
#它唯一的实际效果是from模块名import*不会导入以单个下划线开头的变量。
#2.强私有方法和属性名称的开始处有一个双下划綫
#   Span类的__h方法可以通过：  _Span__h 方法外部访问

#@property属性装饰器
#它们是通过将属性装饰器放在一个方法上面创建的
#这意味着当访问与方法同名的实例属性时，方法将被调用
#属性的一种常见用法是使属性为只读。

#属性也可以通过定义setter/getter 函数来设置
#setter函数设置相应的属性值
#getter函数获取相应的属性值
