class List(list):
def __matmul__(self,other):
newlist = List()
for k in range(len(other)):
newlist.append(self[k]+other[k])
return newlist
l1 = List((1,2,3,4,5))
l2=List((9,8,7,6,5))
l3= l1 @ l2
print(sum(l3))

Output: 50

Answer 1

Shantanu

Here we are adding two list so final list is

[10, 10, 10, 10, 10]

And sum of this list is 50

Answer 2

Shantanu

Role of '@' depends on magic method __matmul__

if you change this method then '@' will not work.
