#metaclass是类的模板,所以必须从`type`类型派生:classListMetaclass(type):def__new__(cls, name, bases, attrs): attrs['add'] =lambdaself, value: self.append(value)returntype.__new__(cls, name, bases, attrs)#继承了list类,在此基础上再做metaclass操作#它指示Python解释器在创建MyList时,要通过L...
这两者非常像,都是源于C++或JAVA中static的思想。不过我觉得,python的静态方法是从c++和java进化时的一个不完全产物。尽量使用类方法,不使用静态方法。 python的实例属性、类属性对应c++或java中的非静态属性和静态属性 python的实例方法、类方法对应c++或java中的非静态方法和静态方法 下面是一个类方法比静态方法牛逼...
