Difference between 'cls' and 'self' in Python classes?

Question

Why is cls sometimes used instead of self as an argument in Python classes?

For example:

class Person:
    def __init__(sel         


        

Answer 1

cls implies that method belongs to the class while self implies that the method is related to instance of the class,therefore member with cls is accessed by class name where as the one with self is accessed by instance of the class...it is the same concept as static member and non-static members in java if you are from java background.
