What are instance variables in Python?

Can you explain what instance variables are in Python?

Sure! Instance variables are attributes that are specific to an instance of a class. They are defined within methods and are usually prefixed with 'self.'

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

Of course! Here's a simple example:

class Dog:
    def __init__(self, name, age):
        self.name = name  # instance variable
        self.age = age    # instance variable

my_dog = Dog('Buddy', 3)
print(my_dog.name)  # Output: Buddy

What happens if I don't use 'self' when defining instance variables?

If you don't use 'self', the variable will be treated as a local variable within the method, not an instance variable.

Are instance variables the same as class variables?

No, instance variables are unique to each instance, while class variables are shared across all instances of a class.
