There are more similar patterns. Let's continue with the series! A third structural pattern to look at is the bridge pattern. We can actually com.. 2023. 3. 22. The Decorator Pattern 5 The Decorator Pattern As we saw in the previous chapter, using an adapter, a first structural design pattern, you can adapt an object implementing a given interface to implement another interface. This is called interface adaptation and includes the kinds of patterns that encourage composition over inheritance, and it could bring benefits when you have to maintain a large codebase. A second in.. 2023. 3. 22. The Adapter Pattern 4 The Adapter Pattern In the previous chapters, we have covered creational patterns, object-oriented programming patterns that help us with object creation procedures. The next category of patterns we want to present is structural design patterns. A structural design pattern proposes a way of composing objects for creating new functionality. The first of these patterns we will cover is the adapt.. 2023. 3. 22. Other Creational Patterns 3 Other Creational Patterns In the previous chapter, we covered a third creational pattern, that is, builder, which offers a nice way of creating the various parts of a complex object. Besides the factory method, the abstract factory, and the builder patterns covered so far, there are other creational patterns that are interesting to discuss, such as the prototype pattern and the singleton patte.. 2023. 3. 22. The Builder Pattern 2 The Builder Pattern In the previous chapter, we covered the first two creational patterns, the factory method and abstract factory, which both offer approaches to improve the way we create objects in nontrivial cases. Now, imagine that we want to create an object that is composed of multiple parts and the composition needs to be done step by step. The object is not complete unless all its part.. 2023. 3. 22.

Index Mastering Python Design Patterns Second Edition Preface Python is an object-oriented scripting language that is used in a wide range of categories. In software engineering, a design pattern is a solution for solving software design problems. Although they have been around for a while, design patterns remain one of the hot topics in software engineering and are a good source of information for so.. 2023. 3. 22. Fundamental Algorithmic Trading Strategies 9 Fundamental Algorithmic Trading Strategies is chapter outlines several algorithms profitable on the given stock, given a time window and certain parameters, with the aim of helping you to formulate an idea of how to develop your own trading strategies. In this chapter, we will discuss the following topics: What is an algorithmic trading strategy? Learning momentum-based/trend-following strateg.. 2023. 3. 20. Introduction to Zipline and PyFolio 8 Introduction to Zipline and PyFolio In this chapter, you will learn about the Python libraries known as Zipline and PyFolio, which abstract away the complexities of the backtesting and performance/risk analysis aspects of algorithmic trading strategies. ey allow you to completely focus on the trading logic. For this, we are going to cover the following main topics: Introduction to Zipline and .. 2023. 3. 20. 이전 1 ··· 27 28 29 30 31 32 33 ··· 46 다음
