inspect.isbuiltin(object):是否为built-in函数或built-in方法
inspect.isroutine(object):是否为用户自定义或者built-in函数或方法
inspect.isabstract(object):是否为抽象基类
inspect.ismethoddescriptor(object):是否为方法标识符
inspect.isdatadescriptor(object):是否为数字标识符,数字标识符有__get__ 和__set__属性; 通常也有__name__和__doc__属性
inspect.isgetsetdescriptor(object):是否为getset descriptor
inspect.ismemberdescriptor(object):是否为member descriptor
