How do I use instance variables in Python?

Instance variables are attributes that belong to an instance of a class. You define them in the constructor using 'self'.

Can you give me an example of how to define an instance variable?

Sure! Here's a simple example:

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

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

What if I want to change the value of an instance variable?

You can change it directly by accessing the instance variable. For example:

my_dog.name = 'Max'
print(my_dog.name)  # Output: Max

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 the class.
