You have this solution in Java, I am interested in this same solution for Python.One interesting application of two-dimensional arrays is magic squares. A magic square is a square matrix in which the sum of every row, every column, and bothdiagonals is the same. Magic squares have been studied for many years, and there are some particularly famous magic squares. In this exercise you will write code todetermine whether a square is magic.You should find that the first, second, and...
