Python Operators

Python Operators in general are used to perform operations on values and variabls. 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.

• Arithmetic Operators

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

  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

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

x ** y

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)
