I am trying to write a Sudoku game with user input. So the user can choose what row/column it wants to and what number. I have to import it from a text file and have made a save and load function.

I have tried starting with what I know, but I don't know how to proceed, ex. how to make the board correspond with the user input.

main code

row = int(input('Hvilken rad vil du endre? ')) #changing row
nytt_tall = int(input('Hva skal det nye tallet være? ')) #asking what number the user would likebrett[row - 1][col - 1] = nytt_tallprint('Ditt nye brett:\n') #printing out the board, with the new input numberbruker.print_board(sudoku_brett)

def check_input(user_input):if user_input.isdigit():if 1 <= int(user_input) <= 9:return Trueprint ("Det kan kun være tall mellom 1-9. Prøv igjen") #telling it can only be number from 1-9return Falsedef print_board(board):for row in board:print(row)def generate_empty_board():return [[[[0 for i in range(3)] for i in range(3)] for i in range(3)] for i in range(3)]print_board(generate_empty_board())

save_load.py

 def readFromFile(filename):f = open(filename,'r')innhold = f.read()print(innhold)f.close()def save(filename, board):f = open(filename, 'sudoku_brett')pickle.dump(board, f)f.close()print("Brett lagret") #saveddef load(filename):f = open(filename, 'sudoku_brett')board = sudoku_brett(f)f.close()print("Brett lastet") #loadedreturn board

The only way it would work in the terminal from what I know is to wait for user input, and they then enter the row, column and number into the terminal. Here is an example:

row = input("Enter a row: ")
col = input("Enter a column: ")
num = input("Enter a number to insert into the grid: ")

And then you would use the values entered to draw the updated grid which you would print to the terminal again, and then await user input again.
