With three arguments, return a new type object. This is essentially a dynamic form of the class statement. The name string is the class name and becomes thenameattribute. The bases tuple contains the base classes and becomes thebasesattribute; if empty, object, the ultimate base of all class...
调用对象方法的语法是instance.method(arguments)。它等价于调用Class.method(instance, arguments)。当定义对象方法时,必须显式地定义第一个参数,一般该参数名都使用self,用于访问对象的内部数据。这里的self相当于C++, Java里面的this变量,但是我们还可以使用任何其它合法的参数名,比如this 和 mine 等,self与C++,Java...
