Note: In Python, there is no command to declare variables. In this variable is created when
you assign a value to it and the data type of the variable can be assigned by using typecasting.
Typecasting refers to convert the variable data type into another data type.

Example 2: b=8
C= 'Hello'
y = int(6) //y will be saved as 6

PERFORMING OPERATIONS ON VARIABLES
Variable is a storage area, which defines the size, layout, range set of operations to be
performed on variable.
Once you declare the data types, you will learn to perform the operations on the data types.
Operator: It is a symbol which operates on a value assigned to a variable. Example: +,-, *, \.
Operand: It is a value on which the operator performed operation.
Arithmetic operators
Arithmetic operation combines two or more numeric expressions by using the arithmetic
operators. The arithmetic operators perform operations such as: addition, subtraction,
multiplication, division, and modulus. In the table given below, we are taking, value of
variable a= 10, and of b=30.
