classmethod

Python built-in functions (60) -- classmethod, pythonclassmethod English document: staticmethod(Function) Return a static methodFunction. A static method does not receive an implicit first argument. The@staticmethodForm is a function decorator-see

A static method is unbound, just like a normal function, except that it needs to be called through a class or instance. No implicit parameters.Instance methods are for instances, class methods are for classes, they can be inherited and redefined,

Test-driven Development (TDD) development model is not a novelty today, its development thinking is in the development of a product function, the firstWrite the test code of the function, in writing development such as, for example, to write a

Python Staticmethod and Classmethod Though Classmethod and Staticmethod is quite similar, there ' s a slight difference in usage for both Entities:classmethod Must has a reference to a class object as the first parameter, whereas

In front of the descriptor, this thing actually and Java setter,getter a bit like. But what does this descriptor have to do with the functional approach we started with earlier? All functions can be descriptor, because it has __get__ methods.

http://blog.csdn.net/pipisorry/article/details/49516185In the design of face object, class method and static method are the two terms commonly used.Logically: A class method can only be called by a class name, and a static method may be called by a

This article describes how to use Decorator in Python to simplify metaprogramming. it is from the IBM official Developer Technical Documentation. if you need Decorator, refer Less effort and more Decorator has something in common with the

Less labor, more. Decorator has something in common with the metaprogramming abstractions introduced before Python: Even without these technologies, you can implement the functionality they provide. As Michele Simionato and I pointed out in an

Python makes metaprogramming possible, but every version of Python has a few nuances (and not completely compatible), which makes the path to metaprogramming more rugged. The use of a class of function objects has a long history, and there are also

Python descriptor (2), pythondescriptor As mentioned above, descriptor is actually a bit like Java's setter and getter. But what is the relationship between this descriptor and the function methods we mentioned above?   All functions can be
