Question

Write a function called find_max that takes a two-dimensional list as a parameter and returns the number of the row that sums to the greatest value. For example, if you had the following list of lists:
list = [[1, 2, 3], [2, 3, 3], [1, 3, 3]]

The first row would be 6, the second 8 and the third 7. The function would, therefore, return 1.
You can assume the passed in list of lists has at least one row and one column. You cannot assume that it is square.

Answer 1

def find_max(lst):
    s = None
    for x in lst:
        tempSum = 0
        for y in x:
            tempSum += y
        if(s == None):
            s = tempSum
        elif(s < tempSum):
            s = tempSum
    count = 0
    for x in lst:
        tempSum = 0
        for y in x:
            tempSum += y
        if(s == tempSum):
            count += 1
    return count

#Testing
print(find_max([[1, 2, 3], [2, 3, 3], [1, 3, 3]]))

Output:

1
