PYTHON 3:

An n x n matrix forms a magic square if the following conditions are met:

1. The elements of the matrix are numbers 1,2,3, ..., n²

2. The sum of the elements in each row, in each column and in the two diagonals is the same value.

Question: Complete the function that tets if the given matrix m forms a magic square.

def is_square(m): '''2d-list => bool Return True if m is a square matrix, otherwise return False (Matrix is square if it has the same number of rows and columns''' for i in range(len(m)): if len(m[i]) != len(m): return False return True

def magic(m): '''2D list->bool Returns True if m forms a magic square Precondition: m is a matrix with at least 2 rows and 2 columns '''

if(not(is_square(m))): return False

#and this is where I need help on what code can complete this
