我正在制作一款《Connect Four》游戏，我希望当你点击一个按钮时，它能够创造出一个红色/黑色圆圈的图像，这取决于你的回合，使用tkinter画布的特定坐标。我创建了一个逻辑和GUI类，但我不能让逻辑类看到画布，因为出于某种原因，它说画布不在GUI中。
AttributeError: type object 'GUI'没有属性'canvas'
逻辑类:
class ConnectFour:
def __init__(self):
self.__grid = []
self.__value = ""
self.__turn = ""
#self.canvas = GUI.canvas
def buttonOneCallback(self):
self.__value = 0
self.getColumnNumber()
self.runGame()
def findLowest(self, grid, columnNum):
board = grid
for y in range(BOARD_Y-1, -1, -1):
if board[y][columnNum] == 0:
return y
def changeValue(self, grid, row, turn, columnNum):
grid[row][columnNum] = turn
return turn
def getPieceColor(self):
color = ""
if self.__turn == PLAYER1:
color = "self.__redImage"
if self.__turn == PLAYER2:
color = "self.__blackImage"
return color
def runGame(self):
#from GUI import GUI
#gui = GUI()
turn = self.setPlayerOrder()
grid = self.makeGrid()
gameInPlay = True
if gameInPlay:
turn = self.getTurnNumber()
if turn == PLAYER1:
#columnNum = int(input("Pick a column: "))
columnNum = self.getColumnNumber()
#print(grid)
#print(columnNum)

self.changeValue(grid, row, PLAYER1, columnNum)
#print(grid)
GUI.placePiece(GUI.canvas,columnNum, row)

gameInPlay = False
result = messagebox.askyesno("YOU WON! Play again?")

#Buttons to choose where to drop the chip

self.canvas.pack()
#Pieces on board
#self.__canvas.create_image(116, 430, image = self.__redImage)
#self.__canvas.create_image(194, 352, image = self.__blackImage)
self.__win.mainloop()
def placePiece(canvas,columnNum, row):
game = ConnectFour()
placementY = (468/6) * (columnNum+1)
placementX = (546/7) * (row+1)

GUI()
谢谢!
在设置GUI类中的canvas属性之前，您正在创建ConnectFour对象。在创建ConnectFour实例之前，您需要确保已经创建了所有依赖项。
