VARIABLES AND DATA TYPES
Variable is a name given to a location in the memory, to store values or data. Usually
variables are used to hold one or more values, result of calculations, etc. In Python, when a
variable is created it assigns a space to a variable in the memory. You can change the value
of the variable assigned when the program is running.
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.
Python has several in-built data types.
The three basic data types in Python are:
String (str)
It represents alphanumeric characters and stores sequence of characters.
It is used for the combination of any character which appears on keyboard (letters,
numbers, symbols).
Characters are enclosed in either single quotes or double quotes or triple quotes.
‘+’ symbol is used to join two or more than two strings together.
