Problem in Magic Methods(Python)

Question

class UnderstandingMagicMethod:
def __init__(self, other):
self.other=other

def __mul__(self,another):
x="*"*len(another.other)
return "\n".join([self.other,x,another.other])

spam = UnderstandingMagicMethod("Hello")
eggs = UnderstandingMagicMethod("World")
print(spam*eggs)

All I expected is:
Hello
*****
World
But I get:
TypeError: unsupported operand type(s) for *: 'UnderstandingMagicMethod' and 'UnderstandingMagicMethod'

So, could please anyone clarify the problem with my code???

Answer 1

Maybe an indentation problem with __mul__. This works:
----------------------
class UnderstandingMagicMethod:
def __init__(self, other):
self.other=other

def __mul__(self,another):
x="*"*len(another.other)
return "\n".join([self.other,x,another.other])

spam = UnderstandingMagicMethod("Hello")
eggs = UnderstandingMagicMethod("World")
print(spam*eggs)
