I’m new to Python and couldn’t find a more intuitive solution for this problem, so I thought I’d share mine. Feedback or improvements are very welcome!

My Pyhton solution:

def hourglassSum(arr): # Write your code here

evey_sum_hourglass_1 = []
evey_sum_hourglass_2 = []
evey_sum_hourglass_3 = []
evey_sum_hourglass_4 = []

for i in range(0,4, +1):

    line_sum_1 = arr[i +1][1]
    for j in range(0, 3, +1):
        line_sum_1 += arr[i][j] + arr[i+2][j]
    evey_sum_hourglass_1.append(line_sum_1)    

for i in range(0,4, +1):

    line_sum_2 = arr[i +1][2]
    for j in range(1, 4, +1):
        line_sum_2 += arr[i][j] + arr[i+2][j]
    evey_sum_hourglass_2.append(line_sum_2)

for i in range(0,4, +1):

    line_sum_3 = arr[i +1][3]
    for j in range(2, 5, +1):
        line_sum_3 += arr[i][j] + arr[i+2][j]
    evey_sum_hourglass_3.append(line_sum_3) 

for i in range(0,4, +1):

    line_sum_4 = arr[i +1][4]
    for j in range(3, 6, +1):
        line_sum_4 += arr[i][j] + arr[i+2][j]
    evey_sum_hourglass_4.append(line_sum_4)   

all_sum = evey_sum_hourglass_1 + evey_sum_hourglass_2 + evey_sum_hourglass_3 + evey_sum_hourglass_4

max_sum = max(all_sum)


return max_sum
