Data Types

Introduction

In programming, all stored data can be classified into one of five data types.

These are

• Character
• String
• Integer
• Real
• Boolean

During this section you will learn to identify each of these.

Data Types

Character

A character is a single letter or symbol.

In Python, a character will be surrounded by quotation marks.

For example:

• "A"
• "M"
• "@"

String

A sequence of characters (letters, numbers, and symbols).

In Python, a string will be surrounded by quotation marks.

For example:

• "Car"
• "15 Park Avenue"
• "Steven"

Integer

A positive or negative whole number, without decimals.

For example:

• 1
• 73
• -45

Real

A number which contains a decimal point.

For example:

• 7.32
• -42.5
• 2.0

Boolean

A data type that only has 2 possible values

For example:

• True / False
• Yes / No
• On / Off

When using python, a boolean is defined as True or False
