Overview of this book

Python is a great language to get started in the world of programming and application development. This book will help you to take your skills to the next level having a good knowledge of the fundamentals of Python. We begin with the absolute foundation, covering the basic syntax, type variables and operators. We'll then move on to concepts like statements, arrays, operators, string processing and I/O handling. You’ll be able to learn how to operate tuples and understand the functions and methods of lists. We’ll help you develop a deep understanding of list and tuples and learn python dictionary. As you progress through the book, you’ll learn about function parameters and how to use control statements with the loop. You’ll further learn how to create modules and packages, storing of data as well as handling errors. We later dive into advanced level concepts such as Python collections and how to use class, methods, objects in python. By the end of this book, you will be able to take your skills to the next level having a good knowledge of the fundamentals of Python.

Object-oriented programming overview


The concept of object-oriented programming was seen to solve many problems, which procedural programming did not solve. In object-oriented programming, everything mimics just like a real-world object. In the real world, everything is an object. An object can have state and behavior. An object in the real world can communicate with another object. For example, a dog object in the real world has state and behavior. OOPs is based on four pillars. They are:

  • Polymorphism
  • Inheritance
  • Abstraction
  • Encapsulation

Key concepts

OOPs is a vast topic that needs to be covered at the intermediate level. In case of Python programming, however, we will cover some key concepts in this chapter.

  • Class: Class is considered as a blueprint for object creation. It can be understood as a factory to produce objects. It provides a template for creating an object and specifying its behavior through means of methods and state through means of variable instance name.
  • Objects: They can be considered...
