静态方法Static Methods 静态方法这个特性我写到现在从没用上过,说实话感觉有点鸡肋。静态方法不与类实例绑定,而是属于一个类。所以他不需要self参数来做指引。 一般来说,我唯一能想到静态方法的使用场景就是写一些utility function,来看个例子: class Pizza(object): @staticmethod def mix_ingredients(x, y): retu...

Python中的类分为新类和旧类。旧类是Python3之前的类,旧类并不是默认继承object类,而是继承type类。 在Python3中所有的类均默认继承object,所以并不需要显式地指定object为基类。 以object为基类可以使得所定义的类具有新类所对应的方法(methods)和属性(properties)。
In general, an object consists of both internal data and methods that perform operations on the data. 通常,对象由内部数据和对数据执行操作的方法组成。 We have actually been using objects and methods all along,such as when working with building types like lists and dictionaries. 事实上,我们一直在...
