What is Instance Variable in Python
In Python, an instance variable is a variable that is defined inside a class and belongs to a specific instance (or object) of that class. Each object can have its own set of instance variables that store data unique to that object. Instance variables are useful for storing and maintaining state information for individual objects, allowing them to have different properties and behaviors even if they belong to the same class. This makes objects more versatile and adaptable, enabling them to encapsata specific to their own instance.

1 - An instance variable in Python is a variable that belongs to a specific instance of a class.
2) Each instance of a class can have its own set of instance variables, which are unique to that instance.
3) Instance variables are defined within a class's methods and are accessed using dot notation (instance_name.variable_name).
4) These variables are used to store data that is specific to each instance of a class.
5) Instance variables are initialized within the class's constructor method (__init__) using the self keyword.
6) Instance variables can have different values for different instances of the same class.
7) Instance variables can be of any data type integers, strings, lists, dictionaries, etc.
8) Instance variables are important for encapsulation and ensuring data integrity within instances of a class.
9) Modifying an instance variable of one object does not affect the instance variables of other objects of the same class.
10) Instance variables can be accessed and modified within the class's methods as well as from outside the class.
11) Instance variables help in achieving the concept of stateful objects in object oriented programming.
12) The value of an instance variable can be changed during the runtime of the program.
13) Instance variables have instance level scope, meaning they are accessible only within the specific instance.
14) Understanding how to work with instance variables is essential for creating object oriented programs in Python.
15) Implementing instance variables correctly is crucial for maintaining the individual states of different objects in a program.
