Single Inheritance, multiple inheritance and multilevel inheritance in python.

Multilevel inheritance in python 

A program as an example.

Code -

--------------------------------

class ElectronicDevice:

    refrigerator = 1000


    def __init__(self, name, watt):

        self.name = name

        self.watt = watt


    def rupee_checker(self):

        elif self.watt > 1000:

            return f"Your Electrical Device consumes more than {a} units per year."

        elif self.watt == 1000:

        elif self.mah > 30 or self.mah == 30:

            return "Your gadget's battery will give backup up to 20 days after full charging"

        elif self.watt > 33:

            return "Your charger is absolutely a fast charger."

        elif self.watt == 33:

            return "Your charger is a fast charger."

 Should we start preparation for BCA/MCA from class 11th ? How ? There isn't much to prepare for BCA/MCA while in class 11th. Just few basics thing to take in mind. Anyhow, Try that you have Computer science in class 11. While all works fine, both computer science and maths are pretty useful. Maths not so much as computer science but will definitely be useful. Science or other subjects aren't really needed that much in most times and if needed you can always learn the topic later on or take help from a knowledgeable person in that field. Make sure to learn at least few programming languages and polish your skills on it. Do focus on algorithm part - That's important. Try to learn different but revelant topics like Cloud Computing or Artificial Intelligence, Cryptography, Networking, etc. Do the one that will be best for you(Depending on which career you want to go for). You can and actually should learn basics behind how actually computers and rest of stuff work. You will be...
