How do I use 'self' in Python?

In Python, 'self' refers to the instance of the class. It's used to access variables and methods associated with the class.

Can you give me an example of how 'self' is used in a class?

Sure! Here's a simple example:

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

    def bark(self):
        return f'{self.name} says woof!'

In this example, 'self.name' refers to the name attribute of the Dog instance.

What happens if I don't use 'self' in a method?

If you don't use 'self', Python won't know which instance's attributes or methods you're referring to, leading to errors.

Are there any alternatives to using 'self'?

In Python, 'self' is the conventional name, but you can technically use any name. However, it's best to stick with 'self' for clarity.
