## Arithmetic Operators

Python includes the +, -, *, /, % (modulus), and ** (exponentiation) operators

Assume variable a holds 10 and variable b holds 20 then:

**Operator Description Example**

+ Addition a + b will give 30

– Subtraction b will give -10

* Multiplication a * b will give 200

/ Division b / a will give 2

% Modulus b % a will give 0

** Exponent a**b will give 10 to the power 20

// Floor Division 9//2 is equal to 4 and 9.0//2.0 is equal to 4.0

## Comparison Operators

The basic comparison operators such as ==, <, >=, and so forth are used on all

manner of values.

Numbers, strings, sequences, and mappings can all be compared.

The following table shows a list of comparison operators.

**Operator Description**

< less than

<= less than or equal

== equal

> greater than

>= greater than or equal

!= not equal

<> not equal

## Logical Operators

The logical operators and and or also return a Boolean value when used in

a decision structure.

There are three logical operators: and, or, and not.

For example, x > 0 and x < 10 is true only if x is greater than 0 and less than 10

**Operator Description**

and logical AND

or logical OR

not logical NOT
