• Since it doesn't know whether the matrix contains floating point numbers, decimals, or integers, you have to provide the conversion function; but the convenience method takes care of the actual creation of the cost matrix: import munkres cost_matrix = munkres. make_cost_matrix (matrix, lambda cost: sys. maxint - cost)

• So, the above profit-calculation program can be recast as: from munkres import Munkres, print_matrix, make_cost_matrix matrix = [[5, 9, 1], cost_matrix = make_cost_matrix (matrix, lambda cost: sys. maxint - cost) m = Munkres () indexes = m. compute (cost_matrix) print_matrix (matrix, msg = 'Lowest cost through this matrix:') total = 0 for row, column in indexes: value = matrix [row]
