This Single Responsibility Principle(SRP) says- A class should have only one responsibility (and a single reason for it to be changed). Class should have only one job/responsibility, and that job/responsibility should be encapsulated inside that class.
The “Program to Interfaces, Not Implementations” principle is- Design your code to depend on interfaces, and avoid the dependency on concrete classes. The process is to define interfaces that specify required behavior. Classes then implement the interface and allow the system to extend and modify the implementation, without changing the dependent code.
The Composition Over Inheritance(COI) principle is- We should prefer composing objects while creating a complex object, rather than relying on inheritance. This means, whenever possible we should avoid hierarchies of class inheritance, and compose objects of a class when we need it.
This Encapsulate What Varies(EWV) principle is- Isolate the part of the code that is likely to be changed later, by encapsulating them. So that the encapsulation works as a shield for the rest of the code.
Python does access control differently. Let’s discuss access control in Python in depth-
Semantic Versioning(SemVer) is a method of assigning version numbers to each released version of software that indicates the scope of the changes made in that release.
Let’s see how can we install or setup a Laravel application. And what files and directories do we get after the installation is complete.
Getters and setters work as the entry point for managing and manipulating data for an object of a class. In this article, we are discussing the getter, setter, and deleter for the property of a Python class.
Variables are identifiers for some data storage in the programming. We can save some data in memory using a variable, and the variable works as a named identifier of that data storage memory address. PHP variable naming starts with a dollar sign($) and then there is an identifier(variable name). The identifier/name of the variable should … Read more
