Introduction: Object Oriented Programming Python Pdf

Getting Started With Object Oriented Programming Python Pdf, In software development, the design is often considered the step done before programming. This isn’t true; in reality, analysis, programming, and design tend to overlap, combine, and interweave. In this chapter, we will learn:
1) What object-oriented means
2) The difference between object-oriented design and object-oriented programming(Object Oriented Programming Python Pdf)
3) The basic principles of object-oriented design
4) Basic Unified Modeling Language and when it isn’t evil Object-oriented?
Everyone knows what an object is: a tangible “something” that we can sense, feel, and manipulate. The earliest objects we interact with are typically baby toys. Wooden blocks, plastic shapes, and over-sized puzzle pieces are common first objects. Babies learn quickly that certain objects do certain things. Triangles fit in triangle-shaped holes. Bells ring, buttons press, and levers pull.
The definition of an object in software development is not so very different. Objects are not typically tangible something that you can pick up, sense, or feel, but they are models of something that can do certain things and have certain things done to them. Formally, an object is a collection of data and associated behaviors.
So knowing what an object is, what does it mean to be object-oriented? Oriented simply means directed toward. So object-oriented simply means, “functionally directed toward modeling objects”. It is one of many techniques used for modeling complex systems by describing a collection of interacting objects via their data and behavior. If you’ve read any hype, you’ve probably come across the terms object-oriented analysis, object-oriented design, object-oriented analysis and design, and object-oriented programming. These are all highly related concepts under the general object-oriented umbrella. In fact, analysis, design, and programming are all stages of software development. Calling them object-oriented simply specify what style of software development is being pursued.
