Needs to be in Python 3!

The Lo Shu Magic Square is a 3 by 3 grid with the following properties:

The grid contains the numbers 1 through 9 where each number appears exactly once in the grid.

The sum of each row, each column, and each diagonal all add up to the same number, 15

In a program, you can simulate a magic square by using a two-dimensional list. Write a Python program that tests whether or not a 3 by 3 grid is a valid magic square. The program reads the input from a text file named input.txt. Each line in the file contains exactly 9 numbers that correspond to the values in a possible magic square. The first three numbers correspond to the values in the first row, the next three values correspond to the second row, and the last three values correspond to the last row.

The text file looks like this:

4 3 8 9 5 1 2 7 6

8 3 4 1 5 9 6 7 2

6 1 8 7 5 3 2 9 4

6 9 8 7 5 3 2 1 4

6 1 8 7 5 3 2 1 4

6 1 3 2 9 4 8 7 5

5 5 5 5 5 5 5 5 5

This is the code I have so far:

def getMatrix (Empt): for line in open ("text1.txt", "r"): lst = line.split() for rowIndex in range(len(lst)): lst[rowIndex] = float(lst[rowIndex]) Empt.append([lst[0:3], lst[3:6], lst[6:9]]) return(Empt)

def main(): Empt = []

for row in Empt: Empt.append([0]* column) d = getMatrix (Empt) print (d)

main()

I'm a little confused where to go from here and am new to programming. Please help!
