A variable is a named storage location in a computer's memory that is used to hold data or values. It allows programmers to store and manipulate data within a program.
["integer: `age = 25`", "string: `name = 'Alice'`", "float: `price = 19.99`", "boolean: `is_active = True`"]
Variables provide a way to store and manage data that can be used and manipulated throughout a program. They make programs more flexible and allow for dynamic data storage.
Declaring a variable involves specifying its name, while initializing means giving it an initial value. In Python, declaration and initialization happen simultaneously. Python is dynamically typed, so explicit type declaration isn't required.
