Question
A Lo Shu Magic Square is a grid with 3 rows and 3 columns. The Lo Shu Magic Square has these properties:
-A grid that contains the numbers 1-9.
-The sum of each row, each column, and each diagonal all adding up to the same number.
In Python create a program simulatimg the magic square using a two-dimensional list.
Additional details:
-It must throw an exception if any character other than 1 – 9 is selected.
-The program needs to give an message explaining that wrong input has been provided.
-The program should prompt the user until the condition has been satisfied. It should prompt the user to enter a number from 1-9.
-The program can only use each number once.
-When the program starts, it should explain how to play the game. Users who have never heard of it should be able to play. The directions should be clear.
-Show an example of a Lo Shu Magic Square after each game.
-The program should allow users to play the game until they choose to quit. It also must keep track of wins and losses.
The user should be given a choice to choose a list of numbers or set a random list of numbers. Lastly, make sure to implement Turtle Graphics such as a score and square grid.

They have made this decision to reduce inherent human errors during calculation and improve efficiency. They think that these can be achieved by an “advanced calculator” that allows a user to choose an equation, provide the inputs, and calculate the outputs.

- Your goal is to implement an application that reads a file, modify its content, and writes the modification back to the same file. The file includes 2 lines of integers. The first line indicates which integer on the second line has been selected (active). And the second line lists all the integers in the list (maximum of 10). Your application should have a menu that is constantly displayed on the screen (see the menu below). Right below the menu, the program should display list of all integers in the file (second line). Also, it should show which integer is currently selected (active) by displaying an arrow to its left. The user should be able to select a menu item by entering its associated key and pressing the Enter key on the keyboard. “Select Down” selects the next item in the list. If the item at the end of the list is selected, this option selects the first item in the list. “Select Up” selects the previous item in the list.

Programming Exercises 403 program Write a program that reads the contents of the file into a list. The program should then ask the user to enter a charge account number. The program should determine whether the number is valid by searching for it in the list. If the number is in the list, the should display a message indicating the number is valid.
