expected reduce to return the final returned product (single value) but got the recursive representation of computation

Not sure if I m missing something here.. I expected reduce() to return the final returned product (single value) but got the recursive representation of computation instead as seen in the output below..

#understanding reduce
import functools

def prod(x,y):
    return x,y

ls = list(range(1,11))  #[i for i in range(1,11)]
print(functools.reduce(prod,ls))

print(functools.reduce(prod,[1,2,3,4,5,6,7,8,9,10]))

output:

(((((((((1, 2), 3), 4), 5), 6), 7), 8), 9), 10) (((((((((1, 2), 3), 4), 5), 6), 7), 8), 9), 10)

prod x*y no?! you're currently returning a (growing) tuple
