Python Operators

Python Operators in general are used to perform operations on values and variables. These are standard symbols used for the purpose of logical and arithmetic operations. In this article, we will look into different types of Python operators. 

• OPERATORS: Are the special symbols. Eg- + , * , /, etc.
• OPERAND: It is the value on which the operator is applied.

Arithmetic Operators

Arithmetic operators are used to performing mathematical operations like addition, subtraction, multiplication, and division.

• In Python 3.x the result of division is a floating-point while in Python 2.x division of 2 integer was an integer and to obtain an integer result in Python 3.x floored (// integer) is used.

Operator	Description	Syntax
+	Addition: adds two operands	x + y
–	Subtraction: subtracts two operands	x – y
*	Multiplication: multiplies two operands	x * y
/	Division (float): divides the first operand by the second	x / y
//	Division (floor): divides the first operand by the second	x // y
%	Modulus: returns the remainder when the first operand is divided by the second	x % y
**	Power: Returns first raised to power second	x ** y

PRECEDENCE:

• P – Parentheses
• E – Exponentiation
• M – Multiplication     (Multiplication and division have the same precedence)
• D – Division
• A – Addition     (Addition and subtraction have the same precedence)
• S – Subtraction

The modulus operator helps us extract the last digit/s of a number. For example:

• x % 10 -> yields the last digit
• x % 100 -> yield last two digits

Example: Arithmetic operators in Python

• Python3

# Examples of Arithmetic Operator a = 9 b = 4    # Addition of numbers add = a + b    # Subtraction of numbers sub = a - b    # Multiplication of number mul = a * b    # Division(float) of number div1 = a / b    # Division(floor) of number div2 = a // b    # Modulo of both number mod = a % b    # Power p = a ** b    # print results print(add) print(sub) print(mul) print(div1) print(div2) print(mod) print(p)
