Hello, can anyone tell me what is wrong with this code please

Question

I need to complete the code to allow the addition of two Zumo objects, resulting in a new Zumo object with the combination of capacity names of the two juices that have been added.

For example, if you add an orange juice with a capacity of 1.0 and an apple juice with a capacity of 2.5, the resulting juice should have:
name: Orange & Apple
capacity: 3.5
The result basically is this: Orange&Apple (3.5L). I made this code

class Juice:
def __init__(self, name, capasity):
self.name = name
self.capasity = capasity

def __str__(self):
return (self.name + ' ('+str(self.capacity)+'L)')

x = Juice("Orange",32.0)
y = Juice("Apple",23.5)
z = x.name+"&"+y.name
e = x.capasity + y.capasity
print (z,e)

and the result is: Orange&Apple 3.5
But i need the other result: Orange&Apple (3.5L)
For some reason I doesn't work my code in order to get the "(3.5L)" part.
If anyone could help me with this it would be great

Answer 1

anthony silver,
you need __add__() magic method, it needs self, other inside brackets, and because __init__ has name, capasity as arguments, also in __add__() method you need both of them, when you return your function with + operation. (Don't forget "&" between self.name and other.name)
And; at the end you only need print(x + y) nothing more. Hope it helps

Answer 2

Cristian Gabriel Mazzulla espera tienes razón , lo que me hacía falta era poner en
def __add__(self) otro argumento aparte de self así : def __add__(self,x) y ya, tenías razón era algo sencillo

Answer 3

Pay attention to the hint:
"Use the __add__ method to define a custom behavior for the + operator and return the resulting object."

Answer 4

I already understand what you are doing wrong, you are printing the variables separately! You must print a new object that is the sum of both

Answer 5

Cristian Gabriel Mazzulla ok gracias por la ayuda, lo aprecio

Answer 6

Dang! One solution is change the last line to :-> print(z+'('+e+')')

Answer 7

Apart from grammatical errors like misspelling capacity your also made quotation errors like where you typed
return(self.name + '('+str(self.capacity)

Answer 8

First, the spelling capacity capasity

I don't know how to describe it.
The z and e are different objects from Juice, and they will call other __str__

Cristian Gabriel Mazzulla is right. Review will be helpful.

Answer 9

𝓕𝓛𝓨 thanks for the correction, but still doesn't give me the result ( Orange& Apple (3.5L))

Answer 10

Cristian Gabriel Mazzulla exactly for the fact that i want to learn , is why I'm asking for help , because I'm not sure why is not working the code, maybe is something simple but I'm not getting it

Answer 11

Cristian Gabriel Mazzulla even though I changed the __str__ magic method for the __add__ method it still give me the result: Orange&Apple 3.5

Answer 12

Cristian Gabriel Mazzulla You speak Spanish?

Answer 13

To add them correctly is that you must define __add__, so you can simply use it "x + y" and get the result

And yes, hablo español, y el inglés es díficil para mí, se nota? jaja

Answer 14

Cristian Gabriel Mazzulla no, de hecho te entiendo que eso es lo importante, ya puse el método __add__ pero me da un error cuando hago que se imprima el resultado

Answer 15

Bien, puedes compartir tu método __add__?
Lo que debe hacer es sencillo, debe retornar la suma de ambos objetos como un nuevo objeto, lo que tú hiciste en z y e como los valores de un nuevo objeto

Answer 16

Genial! Lo hiciste!🥳 jaja

Answer 17

Cristian Gabriel Mazzulla lol pero sabes que, no me había fijado pero solo me sale una parte así: Orange ( 32.0L) no todo completo, ahora no sé cómo hacer para que salga todo completo así: Orange &Apple (55.5)

Answer 18

No entiendo, te refieres a cuando haces la suma y concatenas los nombres?
Puedes usar el método de strings join, que toma como parámetro una lista de strings, así:
"&".join([self.name, x.name])

No sé si te refieres a eso..

Answer 19

Cristian Gabriel Mazzulla mira lo que pasa es lo siguiente el código se ve asi
class Juice:
def __init__(self, name, capasity):
self.name = name
self.capasity = capasity

def __add__(self,x):
return (self.name + ' ('+str(self.capasity)+'L)')

x = Juice("Orange",32.0)
y = Juice("Apple",23.5)

result = x+y
print (result)

Y cuando le pongo para el resultado me sale así:
Orange (32.0L)
Y no el resto, nose si me explico bien

Cristian Gabriel Mazzulla gracias por la ayuda, es bueno encontrar a alguien que hable español
