Operators in Python

Operators

Operators are those who performs some specific operation. Python has a wide variety of operators.

In the simple language Operators are used to perform operations on variables and values.

In the example below, we use the (+) operator to add together two values:

Example:

Print(10+5)

The various python operators are categorized into:

1. Arithmetic operators
2. Comparison/Relational Operators
3. Assignment Operators
4. Logical Operators
5. Identity Operators
6. Membership Operators
7. Bitwise Operators

Arithmetic Operators

Arithmetic operators are used with numeric values to perform common mathematical operations:

Considering a=10 and b=5

Operator	Name	Description	Example
+	Addition	Add two or more numbers	a+b = 15
-	Subtraction	Subtracts two or more numbers	a-b = 5
*	Multiplication	Multiply two or more numbers	a*b = 50
/	Division	Divide two numbers	a/b = 2
%	Modulus	Give the remainder after dividing first number with second	a%b = 0
**	Exponent	Return exponential (Power) value	a**2 = 100
//	Floor division	Divides tow numbers but gives the quotient but removes the decimal place. But in case of Negative value it floors the number to far from zero.	a//b = 2

Comparison Operators

Comparison/Relational operators are used to compare two values that performs comparison among operands. It gives either true or false based on the condition. Comparison/Relational operators are:

Considering a=10 & b=5

Operator	Name	Description	Example
==	Equal	Check whether the first number is equal to second number	a==b returns false
!= Or <>	Not equal	Check whether the first number is not equal to second number	a!=b returns true a<>b returns true
>	Greater than	Checks whether first number is greater than second	a>b  returns true
<	Less than	Checks whether first number is smaller than second.	a<b returns false
>=	Greater than or equal to	Checks whether first number is greater than or equal to second number or not	a>=b returns true
<=	Less than or equal to	Checks whether first number is smaller than or equal to second number or not	a<=b returns false
