In Python, the self keyword is used to define attributes and methods that belong to an instance of a class. Here's a detailed explanation of why the self keyword is used for attributes:

Purpose of self

1. Instance Context:

• The self keyword represents the instance of the class. When you create an instance of a class, self allows each instance to access its own attributes and methods.

• It distinguishes between class-level and instance-level attributes and methods.

• Using self ensures that attributes are stored in the instance's namespace rather than the class's namespace. This is crucial because it allows each instance to maintain its own state.

• Without self, attributes would be shared across all instances, which is generally not desired.

• Python's philosophy emphasizes explicit over implicit behavior. By using self, it's clear that the attributes and methods belong to the instance, improving code readability and maintainability.
