• Defining a class in Python is done using the class keyword, followed by an indented block with the class contents. class <Classname>: data1 = value1... dataM = valueM def <function1>(self,arg1,...,argK): <block>... def <functionN>(self,arg1,...,argK): <block> General Format Class data attributes Class member functions

Python is an Object Oriented programming (OOP). It is a way of programming that focuses on using objects and classes to design and build applications.

Python, an Object Oriented programming (OOP), is a way of programming that focuses on using objects and classes to design and build applications.. Major pillars of Object Oriented Programming (OOP) are Inheritance, Polymorphism, Abstraction, ad. Encapsulation.

Regarding this lecture, in what follows, I’ll start with the main concepts of OO programming in general and then devote the rest of the material to Python OO. The material that I present is drawn from Chapter 3 of my book Scripting with Objects [The book title is a clickable link].

Everything in Python is really an object. We’ve seen hints of this already... These look like Java or C++ method calls. New object classes can easily be defined in addition to these built-in data-types. In fact, programming in Python is typically done in an object oriented fashion.

Many object-oriented programming languages allow the programmer to specific the level of access to the methods and attributes of an object, using Public, Protected, and Private. Python does not have an equivant access control mechnaism, but by convention a method or attribute with no underscores at the start of its name is consdiered to be

• Introduces Python’s special methods to realize class definition, inheritance, multiple inheritance, accessibility, polymorphism, encapsulation. • This presentation indicates the difference of how to realize OOP method between python and other OOP language • Compare Python’s OOP methods with other OOP languages.

Each object has its own species, name, and color. The self argument is necessary to hold information for multiple instances of an object. The Main Method: Convention or Requirement? When I execute (run) animal_main.py, what gets printed? What happens when I …

This is a short course that introduces the basic concepts of OOP. It then goes into more detail explaining how to build and manipulate objects. While this course does not provide an exhaustive discussion of OOP in Python, by the end of the course attendees should be able to build sophisticated objects to aid analysis and research.

Key Words: Object Oriented Concepts, Python, Class Diagrams, Classes, Objects, Polymorphism, Data Abstraction, Inheritance. 1. INTRODUCTION . Object Oriented Programming or OOP as it is more commonly abbreviated as, is the process of implementing the program in terms of objects and classes.
