python design patterns

in Gof's design patterns:elements of reusable object-oriented software, three classes (creation [abstraction of the instantiation process of a class], structural type [ Describes how to combine a class or object to form a larger structure], behavior [to divide responsibility between different objects and abstract the algorithm]) 23 design patterns, including: abs

23 Types of Java design pattern analysis I. Overview of Design Patterns In general, design patterns fall into three broad categories: Create five types of models: Factory method mode, abstract Factory mode, singleton mode, builder mode, prototype mode. Structure mode, a tot

Design Pattern. This concept is now full of sky and we can estimate it in our hands: Erich Gamma, Richard Helm, Ralph Johnson, and John Vlissides, in the book "Design Patterns-Element of Re-Useable Object-Oriented Software", this book. There are three modes, creation mode, structure mode, and behavior mode. There are 23 modes in total, which are not listed here.

summarize which types of design patterns are used to solve the problems (this will be reflected in each mode) (5) basic conditions for learning the design model As the saying goes, "if you want to exercise your power, you must first go to the palace, even if you do not succeed ." This

Six principles of design patterns (6) -- six principles of open and closed Design Patterns Definition: The objects (classes, modules, functions, etc.) in the software should be open to extensions, but the modifications should be closed. Personal Understanding: In general, the open/closed principle refers to various com

Common iOS design patterns-prototype and ios Design Patterns1. What is the prototype? (What) The prototype is a creation design mode. It creates an object quickly by copying it. There are two ways to copy it: 1 .) shortest copy (pointer copy); 2 .) deep copy (value copy); it is more efficient to create a new object in

Statement in advance: I am referring to Chen and Wang Bin's "grinding design mode" for the study of design models. I am reading this book carefully and think it is quite good. Then, I sorted out some knowledge points in the book. Although they were not original in the true sense, I also sorted out some other knowledge points, so I dared to write originality on my blog. I hope the author of this book will no

I have only been studying programming for two years and have not done any big applications yet. I joined the C language and made several small games such as Russian. Sophomore contacts win api and DX and understands C ++. At that time, I really felt that C ++ had nothing to do. It was just a high-level C. But later, I gradually discovered the depth of object-oriented design. Write in C ++ Program It is really difficult. Unlike C, it adds functions to

Both of them should depend on abstract interfaces. Abstract interfaces should not depend on specific implementations. The specific implementation dep
