Python Logical Puzzles, Games, and Algorithms: Lo Shu Magic Square

**Python Homework Solution**

The Lo Shu Magic Square is a grid of nine squares, traditionally filled with the numbers 1 through 9. The challenge is to arrange the numbers such that each row, column, and diagonal adds up to the same number (15).

Here's a Python code to check if a given square is a Lo Shu Magic Square:

def is_lo_shu_magic_square(square):

# Check if all rows, columns, and diagonals add up to 15

row1_sum = sum(square[0])

row2_sum = sum(square[1])

row3_sum = sum(square[2])

col1_sum = square[0][0] + square[1][0] + square[2][0]

col2_sum = square[0][1] + square[1][1] + square[2][1]

col3_sum = square[0][2] + square[1][2] + square[2][2]

diag1_sum = square[0][0] + square[1][1] + square[2][2]

diag2_sum = square[0][2] + square[1][1] + square[2][0]

if row1_sum == row2_sum == row3_sum == col1_sum == col2_sum == col3_sum == diag1_sum == diag2_sum == 15:

return True

else:

return False

The function is_lo_shu_magic_square takes a 2-dimensional list representing the square as its input parameter. It checks if all the rows, columns, and diagonals add up to 15, and returns True if it is a Lo Shu Magic Square, and False otherwise.

Here's an example of how to use the function:

# Example square

square = [[4, 9, 2], [3, 5, 7], [8, 1, 6]]

# Check if square is a Lo Shu Magic Square

if is_lo_shu_magic_square(square):

print("The square is a Lo Shu Magic Square!")

else:

print("The square is not a Lo Shu Magic Square.")

Output:

The square is a Lo Shu Magic Square!
