What are instance variables in programming?

Instance variables are attributes that belong to a specific instance of a class. They hold data unique to that instance.

Can you give me an example of how to use instance variables?

Sure! In Python, you define an instance variable inside a class using 'self'. For example:

class Dog: def init(self, name): self.name = name

my_dog = Dog('Buddy') print(my_dog.name) # Output: Buddy

What’s the difference between instance variables and class variables?

Instance variables are unique to each object, while class variables are shared across all instances of a class.

How do I access instance variables from outside the class?

You can access instance variables using the object name followed by a dot and the variable name, like this: my_dog.name.
