Understanding the Self Keyword
In object-oriented programming, self refers to the instance of a class. It is the first parameter in instance methods and provides access to the object's attributes and methods, making it essential for working with instance-specific data and behavior.
When a method is called on an object (e.g., my_object.method()), Python automatically passes the instance as the first argument, equivalent to MyClass.method(my_object). The method receives this reference through the self parameter.
It allows objects of the same class to maintain independent data and state while sharing the same methods. It acts as a bridge between methods and the specific object they are called on, ensuring correct behavior based on each object's unique state and making it fundamental to effective class design.
