Here, we can seefoo_objis correctly identified as an instance of classFoo, but the type of classFooindicates that it is an instance of classtype, establishing the point that classes are indeed created by other classes. Creating classes dynamically usingtype()¶ This is one more concept we ...
What are metaclasses (finally) 最后,元类(metaclass) 到底是什么? 元类(Metaclass) 是创建类(class)的东西。你定义了各种各样的类去描述不同的对象(obj),但是通过上面的内容我们已经了解到在Python中类就是对象。元类(metaclasses)就是创建这些类的东西,你可以认为他们是:描述类(class)的类(class)。可能有点...
When theclassstatement is executed, Python first executes the body of theclassstatement as a normal block of code. The resulting namespace (a dict) holds the attributes of the class-to-be. The metaclass is determined by looking at the baseclasses of the class-to-be (metaclasses are inherite...

A property in Python is a tool for creating managed attributes in classes. The @property decorator allows you to define getter, setter, and deleter methods for attributes. You use properties when you need controlled access or want to encapsulate logic without changing the API. Properties are ...
“dir” into the prompt, Python will respond with all of the global functions and classes that are currently loaded. This is a ridiculously powerful tool that’s great to use when exploring new libraries. This reflective vision of the running environment can also be used to examine all of...
See also the excellent Python talk,"Stop Writing Classes", by a Python core contributor. In it, the presenter suggests that if you have built a class with a single method that is named like a class (e.g.Runnable.run()), then what you've done is modeled a function as a class, and...
