这里有英文原句,我不知怎么翻译了,很容易看懂,但不知如何说:There are only two kinds of objects in Python: to be unambiguous let's call these types and non-types. Non-types could be called instances, but that term could also refer to a type, since a type is always an instance of anothe...
在python中只要两种对象:类型和非类型。非类型也被称为实例。这里有英文原句,我不知怎么翻译了,很容易看懂,但不知如何说:There are only two kinds of objects in Python: to be unambiguous let’s call these types and non-types. Non-types could be called instances, but that term could also refer ...

Polymorphism allows you to treat objects of different types as instances of the same base type, as long as they implement a common interface or behavior. Python’s duck typing make it especially suited for polymorphism, as it allows you to access attributes and methods on objects without needing...
在Python3中,类和类型已经是一种东西了。 在Python3 中只有类和非类两种对象。类型是"<class 'type'>" 那么它是类否则它是非类。听起来很绕,英文原文:There are only two kinds of objects in Python: to be unambiguous let's call these types and non-types. Non-types could be called instances, bu...
在Python的世界中,object是父子关系的顶端,所有的数据类型的父类都是它;type是类型实例关系的顶端,所有对象都是它的实例的。 它们两个的关系可以这样描述: object是一个type,object is and instance of type。即Object是type的一个实例。 type是一种object, type is kind of object。即Type是object的子类。
Built-in objects are components of extensions. For more complex tasks, you may need to provide your own objects using Python classes or C language interfaces. But as you’ll see in later parts of this book, objects implemented manually are often built on top of built-in types such as list...
在 Python 中，整数对象是最简单的对象了。对于读者来说，也是最容易真切地感受Python的对象机制的切入点，因此我们对Python所有内建对象的研究就从这个最简单的整数对象开始。Python 中的整数是通过 PyIntObject 对象来实现的。PyIntObject 的对象是一个不变(immutable)对象，也就是说，在创建了一个PyIntObject的...
The standard module types defines names for all standard built-in types. type objects翻译过来就是类型对象, 其表示各种对象的类型,我们可以使用type()去访问任何对象的类型,type和object都属于Type Objects 结合上面的阐述,可以勾勒出python中'对象'这个概念的全貌: object和type是两个原初的对象,由他们派生(...
Python Types and Objects ）才懂的。object 和 type的关系很像鸡和蛋的关系，先有object还是先有type...
