DATA TYPES
Variables contain the values on which the operations are performed. Every variable needs
to be assigned to a specific data type to make it accessible for the computer.
Data type identifies the type of data which the declared variable can hold. It helps the
computer to understand what operations need to be performed on the declared variables.
The common data types are:
Data Type Description Declaration Example
Integer (int) It represents whole numbers (zero, x=4 5, 10, 988
positive, negative value, but not decimal
(fractional) values.
Assigning non-integer value to integer
type variable returns error.
Integer type variable holds only a single
value.
Floating Point It represents real numbers with decimal x= 5.1 4.65, 8.05,
Numbers values or fractions. x= 9.99*8.88 10.1
(float) Another type of floating-point number is
'double' data type, to store even bigger
values.
Character It holds a single letter. (e.g., a.b.c.) x='y' 90 (in ASCII,
(char) The syntax of declaring a character type 90 is a
variable is specific to the programing upper case
language. 'Z')
It is the smallest data type by size.
Assigning a non-character type value to
a character type variable returns error.
String (str) It represents alphanumeric characters x= 'Orange' Coding,
and stores sequence of characters. Fruit,
It is used for combination of any Orange123
character which appears on keyboard
(letters, numbers, symbols).
In python string variables can be
declared either by single quotes or
double quotes or triple quotes.
