## 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 10Operator Descriptionand logical AND or logical OR not logical NOT
