Simple example code. Instance methods must have self as a parameter, but not needed to pass this in every time.

Inside any instance method, use self to access any data or methods that may reside in class. It will not accept them without going through self.

class Student:

    def __init__(self, id, name): = id = name

    def show(self):
        return + " " +

s1 = Student("101", "John")
