type时所有元类的父亲
object是type（object的类型是type），type也是object（type继承自object） >>> isinstance(object, type) True >>> isinstance(type, object) True 在python中一切皆object，所有对象都是从object继承而来的，type也是object，而object的type是type >>> type.__base__ <type 'object'> >>> type(object) <type 'type'> 1、type是一切type的类型 2、object是所有对象的基类，type也继承自object 3、object的type是type 去掉object所有对象都不能用了，而去掉type，所有对象还是可以正常运作的，只是没有一个东西标识他的类型了
