Python Juice maker problem

Question

Somebody please help i am getting error in second last line on doing 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 Juice(self.name + '&' + other.name, self.capacity + other.capacity)

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

result = a + b
print(result)

Answer 1

def __add__ (self, other):

You are adding two objects therefore your dunder/magic method __add__ should be indented inside the class.

Answer 2

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

# adding two objects
def __add__(self, o):
return Juice((self.name + "&" +o.name), (self.capacity + o.capacity))

a = Juice("apple", 1.5)
b = Juice("orange", 2)

c = a + b

print(c.name)
print(c.capacity)

what is wrong with me my code runs on my editor but not sololearn

Answer 3

Abebe Adigo when I pasted your code into SoloLearn's Coding Playground and ran it, I got the correct result without error:

apple&orange
3.5

Answer 4

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 Juice(self.name + '&' + other.name, self.capacity + other.capacity)

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

result = a + b
print(result)

Answer 5

I don't know. My solution is the same, and it passes. Maybe there is a stray unprintable character. Try the 'reset code' option in the hamburger menu and retype it from a clean start.

EDIT: Ah yes, 《 Nicko12 》 found it: indentation error on def __add__.

Answer 6

Tab ??
Return

Answer 7

Excpected Output must be:

Orange&Apple (3.5L)

Your code could be fixed with:

return Juice(o.name.capitalize()+ "&" + (self.name.capitalize()), f"({(self.capacity + o.capacity)}L)")
