I am trying to write a toString() method in an inherited class but it is giving me weird output and I don't know why. New to Python, please help.

This is part of the tutorial Python Programming: https://www.youtube.com/watch?v=N4mEzFDjqtA&feature=youtu.be at minute 39. I tried changing the syntax a bit but the problem remained. Also, it didn't work with a direct call to the variables, as it is done in the video, but I had to use the get methods instead. Not sure why it works for him but not for me.

class Animal:

    __name = ""

    __height = 0

    __weight = 0

    __sound = 0



    def __init__(self, name, height, weight, sound):

        self.__name = name

        self.__height = height

        self.__weight = weight

        self.__sound = sound



    def get_name(self):

        return self.__name

    def get_height(self):

        return self.__height

    def get_weight(self):

        return self.__weight

    def get_sound(self):

        return self.__sound



    def toString(self):

        return "{} is {} cm tall and {} kilograms and says {}".format(self.__name, self.__height, self.__weight, self.__sound)



class Dog(Animal):

    __owner = ""



    def __init__(self, name, height, weight, sound, owner):

        self.__owner = owner

        Animal.__init__(self, name,height,weight,sound)



    def toString(self):

        return "{} is {} cm tall and {} kilograms and says {}. His owner is {}".format(self.get_name, self.get_height, self.get_weight, self.get_sound, self.__owner)





cat = Animal('Whiskers', 33, 10, 'Meow')

print(cat.toString())

dog = Dog('Dida', 33, 10, 'Waf', 'Joshua')

print(dog.toString())

This gives me a result with things like: <main.Dog object at 0x00000243E9870390>> instead of the variables for the dog.toString() output. Instead of the actual variables.

Should be:
Whiskers is 33 cm tall and 10 kilograms and says Meow
Dida is 33 cm tall and 10 kilograms and says Meow. His owner is Joshua

Anyone can explain to me what I am doing wrong?

You have a mix of direct property access and methods, which are function. You can access properties directly like: self.__weight but you need to call the methods: self.get_name() (with ()) otherwise you just print the string representation of the function itself.

A string method more like this should work better:

def toString(self):

    return "{} is {} cm tall and {} kilograms and says {}. His owner is {}".format(self.get_name(), self.get_height(), self.get_weight(), self.get_sound(), self.__owner)
