Data Types

Data Types

Data types define what information is stored

The most used of them are:

Type	Description	Example
numeric	Whole or floating number.	num = 5 num = 7.2
string	Sequence of symbols (text).	text = 'Python is awesome!'
boolean	Can have only 2 values - True or False.	isAwesome = True

Printing Data

It's done using print.

print('Message to print.')

Variables

The variables are used to store data of certain type.

Their value can be changed any time.

Example of variables definitions:

# Declaring variable with value: num1 = 5 num2 = -3 num3 = 7.2 # String values are set in single or double quotes. name1 = 'Alex' name2 = "Smith" letter = 'c' boolVariable1 = True boolVariable2 = False

Basic program example:

Write a program in which variables are defined and printed.

Solution:

device = 'PC' number = 5 print(number, device)

Output:

5 PC
