Help me in the oop code coach

Question

This is my trial

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

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

a = Juice('Orange', 1.5)
b = Juice('Apple', 2.0)

result = a + b
print(result

Answer 1

Implement a __add__ method as if it will be called this way

a.__add__(b)

It should return a new Juice object explicitly.

def __add__(self, additive):
return new Juice(x, y)

Where x and y are the new object's name and capacity respectively.

Answer 2

I solved it
class Juice:
def __init__(self, name, capacity):
self.name = name
self.capacity = capacity

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

def __add__(self,newJuice):

self.name += "&" + str(newJuice.name)
self.capacity += newJuice.capacity
return self.__str__

a = Juice('Orange', 1.5)
b = Juice('Apple', 2.0)

print(a.__add__(b)())

Answer 9

Kintu Michael Evans
I don't know what to describe ...
What you need to add Juice <a> and Juice <b> is to implement __add__ magic method.

Answer 10

Kintu Michael Evans that is why __add__ is called a *magic* method

There is a cheat to that problem just print the answer directly since it has only one test case, believe me it works 😁😁

Answer 13

Kintu Michael Evans WTG! But replace the last line with
