2.13OPERATORS IN PYTHON

Operators are used for performing operations on variables and values.

Python divides the operators into the following groups:

•Arithmetic operators

•Assignment operators

•Comparison operators

•Logical operators

•Identity operators

•Membership operators

•Bitwise operators

Python Arithmetic Operators

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

Table 2.1 Common mathematical operations

Operator	Name	Example
+	Addition	x + y
−	Subtraction	x − y
∗	Multiplication	x ∗ y
/	Division	x / y
%	Modulus	x % y
∗∗	Exponentiation	x ∗∗ y
//	Floor division	x // y

Python Assignment Operators

Assignment operators are used for assigning values to variables.

Table 2.2 Assignment operators

Operator	Example	Same As
=	x = 5	x = 5
+=	x += 3	x = x + 3
−=	x −= 3	x = x − 3
∗=	x ∗= 3	x = x ∗3
