Python Program to Find the List in a list of lists Whose Sum of Elements is the Highest

In this example, we will write a simple program to find the list with the highest sum of elements in the given list and print the result. To better understand this example, make sure you have knowledge of the following tutorials:-

• Python if…else Statement
• Python List
• Python for Loop Statements

num = [[1, 2, 3], [4, 5, 6], [10, 11, 12], [7, 8, 9]]

index = 0
max_index = 0
sum_max = 0
for list in num:
    sum_list = 0
    for x in list:
        sum_list += x
    if sum_list > sum_max:
        sum_max = sum_list
        max_index = index
    index += 1

print(num[max_index])

number = [[1,2,3], [4,5,6], [10,11,12], [7,8,9]]
print(max(number, key=sum))
