Imagine a situation. You stay in a big home with family members cosy and comfortabily (Class in Programming world). Now here comes your American born cousin for a visit, He does not know what is where, How everything works in your home. Your cousin wants to perform some activites (Call some functions in Programming world). 1. Wants to go out in Car. 2. Wants to cook. You are always with him and ensure all the necessity are there so that he can perform all these activites. You always that guiding force that helps him. YOU in this case is that "self" object. Similarly in Python class, when a member function is called by an instance of that class. Function which is being called has a reference to itself called SELF which can access the member variables and other member function through the SELF. So every member function in class when called has invisible SELF object which points to current calling object. In the same way You cousin is able to do all the activities with the help of you.
