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.

Loops


There might be a situation where you might require to run a single block of code a number of times, in that situation, loops come in handy. Loops come handy in situations such as iterating through data structures in any programming language or traversing through large sets of data to filter out junk data, followed by certain keywords followed by alphanumeric characters followed by certain special characters. 

Types of loops

There are two types of loops, namely:

  1. Definite: In this case, the code of block runs for a defined number of times. This is useful when the programmer exactly knows in how many counts the task will be executed or let's assume that he knows the number of elements inside the data structure. For example, the strength of a classroom.
  1. Indefinite: In this case, the code of block runs until the condition is true. This is useful where the count is unknown. For example, trying to figure out the number of times London appears in a literary article.
