What are instance methods in Python?

Can you explain what instance methods are in Python?

Sure! Instance methods are functions defined inside a class that operate on instances of that class.

How do they differ from class methods?

Instance methods take 'self' as the first parameter, while class methods take 'cls' and are called on the class itself.

Can you give me an example of an instance method?

Of course! Here's a simple example:

class Dog:
    def bark(self):
        return 'Woof!'

my_dog = Dog()
print(my_dog.bark())  # Output: Woof!`

What happens if I forget to include 'self' in an instance method?

If you forget 'self', Python will raise a TypeError because it won't receive the instance reference.
