Python Operators

Overview

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)

Although the

+ operator is often used to add together two values, like in the example above, it can also be used to add together a variable and a value, or two variables:

Example sum1 = 100 + 50 # 150 (100 + 50)

Formula

sum2 = sum1 + 250 # 400 (150 + 250)
sum3 = sum2 + sum2 # 800 (400 + 400)

Python divides the operators in the following groups:

Arithmetic operators

Assignment operators

Comparison operators

Logical operators

Identity operators

Membership operators

Bitwise operators
