So This is supposed to be done by last Thursday, and I am STILL working on this assignment, and since it is quarantined so my teacher can't really help me with this work, and I kinda figure it out but it keeps giving me an error of the wrong spot of the code like the "print" is wrong or something like that. I think something is wrong with this code, and I can't figure out why or what is wrong with this code. Can you guys please please please help me with good explanations?

the Title won't let me make my own so I HAD to choose that one. NOT MY FAULT: :)

Answer 1

1. you forgot to pass all argument to the Pet class when you initiated it
2. get__heavier and get__taller used not existed variables

Below is the working copy program

    """
        Object that contains attributes relating to pets

        than second, otherwise returns False.
        is_older: compares two pets' ages. Returns true if self is older
        than second, otherwise returns False.
        Same_colour: compares two pets' colours. Returns True if colours match
        Returns False if Colours don't match.

Answer 2

I think error your generated on the basis of No or argument. if you observe your code

def __init__(self, name, animal_type, age, weight, height):
        self.__name = name
        self.__animal_type = animal_type
        self.__age = age
        self.__heavier = weight
        self.__taller = height

require total 5 argument while you passed only 3 of them

pets = Pet(name, animal_type, age)

correct format

pets = Pet(name, animal_type, age,weight,height)
