As to why they're separate (aside from simple historical reasons): __new__ methods require a bunch of boilerplate to get right (the initial object creation, and then remembering to return the object at the end).
object1=Example()print(object1)# prints'<__main__.Example object at 0x102e26990>'print(Example)# prints'<class '__main__.Example'>'Example_Mirror=Exampleprint(Example_Mirror)# prints'<class '__main__.Example'>' 2. 动态创建 class 由于class 也是 object,因此可以像创建普通 object一样动态...
first= Dynamic_Class_Creater('name1')print(first)#prints '<class '__main__.Class1'>'print(first())#prints '<__main__.Class1 object at 0x105452e10>' 使用class 关键字创建类的时候,Python 会自动创建对应的 object。像 Python 中其他大多数情况一样,我们也可以通过type()创建这个 class object ...

Class也是Object 在理解metaclass之前,我们需要先理解Python中的class。从某种程度上来说,Python中的class的定位比较特殊。 对于大部分面向对象语言来说,class是一段定义了如何产生object的代码块。在Python中这一定义也成立: >>>classexample(object): ...pass...>>> object1 =example()>>>print(object1)<__ma...

Links to Official Documentation Python Tutorial: Class Objects Reading Comprehension Solutions Set Creation: Solution Create a definition for the class of object named Dog. This class should have two attributes: “name” and “speak”. The “name” attribute should bind a string to the ...
Essentially, it is the method responsible for actual object creation. We won’t go in detail into the base implementation of __new__. The gist of it is that it allocates space for the object and returns it. The interesting thing about __new__ is that once you realize what it does,...
