WebMar 18, 2024 · This approach defines a function called “print_diagonals_2” that takes in a matrix as an argument. It then initializes two empty lists to store the elements of the matrix’s diagonals. Using a loop, it iterates through the matrix and appends the elements of the two diagonals to their respective lists. Finally, it prints the two diagonals.
