Python Juice Maker Problem

Question

I have the following code.

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, other):
return (self.name + "&" + other.name, self.capacity + other.capacity)

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

result = a + b
print(result)

Which outputs: ('Orange&Apple', 3.5).
But the output which is required is: Orange&Apple (3.5L)

Does anyone know how to get rid of the ' ' and the , and add brackets around 3.5?

Answer 1

your __add__ method return a tupple instead of a Juice object... you need:

def __add__(self, other):
return Juice(self.name + "&" + other.name, self.capacity + other.capacity)

Answer 2

You can change the return statement of add method to following one,

return f"{self.name}&{other.name}({self.capacity+other.capacity})"

Answer 3

return(self.name+'&'+other.name+ ' ('+str(self.capacity+other.capacity)+'L)')
this shud work,
