A python program

A square array of numbers, usually positive integers, is called a magic square if the sums of the numbers in each row, each column, and both main diagonals are the same. For example, in the following magic square the sum of each row, column, and both main diagonals is equal to 15:

In the module question4.py, create some functions that lets a caller determine if a two-dimensional array of integer values is or is not a magic square.

There must be one function named:

def is_magic(t):

where t is a two-dimensional array (list of lists) of integer values that returns True if t represents a magic square, and False otherwise. The function should not modify the array t.

You should decompose the problem down into separate functions rather than trying to solve the problem all in a single function. A sensible decomposition of the problem into separate functions contributes to your mark for this question.

A user of the module would call your is_magic function like so for the magic square shown above:

t = [[2, 7, 6], [9, 5, 1], [4, 3, 8]] boo = question4.is_magic(t)

Here are some more magic squares for testing purposes:

t = [[8, 1, 6], [3, 5, 7], [4, 9, 2]] t = [[2, 16, 13, 3], [11, 5, 8, 10], [7, 9, 12, 6], [14, 4, 1, 15]] t = [[1, 14, 4, 15], [8, 11, 5, 10], [13, 2, 16, 3], [12, 7, 9, 6]]
