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.

Most of the programming languages provide the if...else if...else control block, while Python has shortened else if to elif but the principle remains the same, that is, it divides the complete control block into number of blocks for specific action to be executed. It can be interpreted with day-to-day examples, for example, if this debit card doesn't work, use this credit card, else pay with a cheque. 

Syntax

if condition-1:
	sequence of statements-1
elif condition-n:
	sequence of statements-n
else:
	default sequence of statements

Here, in the syntax, we are illustrating a series of branching statements under different conditions which is also called conditional branching in any language. First, we encounter an if block and if the condition inside the if block is satisfied or becomes true, only then will the if block be executed. If while executing the condition inside...
