Add the numbers in a 9x9 multiplication Table

Pls give (show) me nice variations in Lisp and Python.  Thanks!!!
 A happy new year! ...
44 x 44 = 1936
45 x 45 = 2025   <--  one reason that  Puzzle nerds are excited today.
46 x 46 = 2116

The following    (in Lisp (Scheme) and Python)    adds
                     all the numbers in a  9x9  multiplication Table.
________________________________
(print (apply +
          (apply append
             (map (lambda (y)
                        (map (lambda (x) (* x y))  (iota 9 1)))
                  (iota 9 1)))))
______________________________________
isum=0
for y in range(1, 10):
    print()
    for x in range(1, 10):
        print(f"{x*y:3}", end=" ")
        isum += x*y
print('  Total= ', isum, '\n')
_______________________________
kuku = [i*j for i in range(1, 10) for j in range(1, 10)]
print(sum(kuku))

i don't see why the Python compiler doesn't
           give me a STERN  warning when it sees that I have this line:
sum=0
