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.

Type Variables and Operators

Operators


Python supports the following types of operators:

  • Arithmetic operators.
  • Comparison operators
  • Assignment operators
  • Bitwise operators
  • Logical operators
  • Membership operators
  • Identity operators

Arithmetic operators

Arithmetic expressions comprise operands and operators:

Operator

Description

**

Exponent: Performs exponential (power) calculations on operands

*

Multiplication: Performs multiplication between operands

/

Division: Performs division between operands

%

Modulus: Performs modulus division between operands

+

Addition: Performs addition between operands

-

Subtraction: Performs subtraction between operands

We have already discussed the precedence order of the operators.

Comparison operators

Like any other language, Python also supports comparison operators. Comparison operators return True or False:

Operator

Description

==

Checks the equality

<

Returns True if the left-hand side operand is less than the right-hand side operand

>

Returns True if the left-hand side operand is greater than the right-hand side...
