Introduction

This page goes over inheritance of object between classes in Python. This is a big part of OOP and making reusable code.

Python super() Function

Supercharge Your Classes With Python super() – Real Python

Python’s super() considered super!

Ex.: My First Example

class SuperClass:

    def __init__(self, money, hourly):
        self.money = money
        self.hourly = hourly

    def show_stats(self):
        return print('Money is {} and your hourly is {}'.format(self.money, self.hourly))

class SubClass(SuperClass):

    def __init__(self, money, hourly):
        super().__init__(money, hourly)

    def yea(self):
        return SuperClass.show_stats(self)

S = SubClass('$300', '$50500')
S.yea()

Seems to do the same thing as Ex. 1, but at least I wrote it myself. I am still now 100% what it does, other than inheriting objects from another class to then use in the subclass, but I can see how this can be useful. I am going to see if I can use this in my EP 425 final project (see EP 425 Semester Project and Project Code Notes)

My Analysis of the code:

• Basically, when you call super().__init__(money, hourly), you are pretending that you are inserting those inputs in the parent class, so then the parent class will have all the goods even thought you inputted them from the subclass.
• You need to use the same inputs in your second class for def __init__(self, money, hourly) since you are now “initializing” them from the child class.
  • Otherwise, the objects cannot be successfully inherited from the child class to the parent class
