Essentially, I am trying to access the value of one function and I’m trying to use it within another function.

This is the current function I have:

 def getMove(self):
        print("Coordinates must range from 0 to 2, 0 corresponding to the first row/column, onwards")
        xcoor = int(input("What is your x coordinate?"))
        ycoor = int(input("What is your y coordinate?"))
        
        if xcoor and ycoor not in range(0,3):
            print("Coordinates must be between 0 and 2")


        return f"({xcoor},{ycoor})"

and I am trying to use the ‘xcoor’ and y’coor’ variables here to set the move with the marker wherever the user specified. I thought that since you can access a 2d array’s individual element and it assign it a value, you could do the same thing when using variables, but this does not appear to be the case. Maybe I don’t understand how classes work when it comes to access or its syntactical issue, either way, some guidance and/or further reading would be appreciated.

def makeMove(board,marker):
        #todo: code to alternate between players
    
        marker = "X"
        #makesmove
        board[xcoor][ycoor] == marker

Full code if needed:

class Tictactoe:

    def __init__(self,playerone,playertwo):
        self.playerone = playerone
        self.playertwo = playertwo
        
        
        
        

    def newBoard(self):
        # creates new board
        return [[None, None, None],
                 [None, None, None],
                 [None, None, None]
                 ]
        
        
        
        


    def renderBoard(self):
        board = self.newBoard()
        
        # Prints current state of the board
        for row in board:
            print("|", end="")
            for cell in row:
                if cell is None:
                    print("   |", end="")
                else:
                    print(f" {cell} |", end="")
            print("n" + "-" * 13)



    def getMove(self):
        print("Coordinates must range from 0 to 2, 0 corresponding to the first row/column, onwards")
        xcoor = int(input("What is your x coordinate?"))
        ycoor = int(input("What is your y coordinate?"))
        
        if xcoor and ycoor not in range(0,3):
            print("Coordinates must be between 0 and 2")

        
        return f"({xcoor},{ycoor})"


    def makeMove(board,marker):
        #todo: code to alternate between players
    
        marker = "X"
        #makesmove
        board[xcoor][ycoor] == marker

        


        

    def getWinner(self):
        #todo write win conditions
        '''if player one marks 3 in a row, player one wins, end game
        if player two marks 3 in a row, player 2 wins, end game
        '''
        pass

    def resetButton(self):
        #todo: create a reset button that clears the board.
        pass

    def runGame(self):
        #todo: write code that starts the game.
        pass

    def isBoardFull(self):
        #todo: write code that checks if board is full
        pass


def main():
    test = Tictactoe("playerone", "playertwo")
    print(test.makeMove())
