如何解决我的代码中产生TypeError的问题？

class Player(object):
    def __init__(self, board):
        self.board = board
        self.x = 607
        self.y = 420
        self.pos = [(self.x, self.y)]

    def movement(self, x, y):
        self.x += x
        self.y += y
        self.pos = [self.x, self.y]

    def draw(self):
        for tup in self.pos:
            if (tup[0] == self.x) and (tup[1] == self.y):
                pygame.draw.circle(self.board.window, (255, 255, 0), (self.x, self.y), 8)

    def update(self):
        pygame.display.update()

Traceback (most recent call last):
   File "C:/Users/fotio_000/PycharmProjects/Pacman/main.py", line 4, in <module>
   board = Board()
   File "C:\Users\fotio_000\PycharmProjects\Pacman\Game.py", line 32, in __init__
   self.all_events()
   File "C:\Users\fotio_000\PycharmProjects\Pacman\Game.py", line 38, in all_events
   self.draw()
   File "C:\Users\fotio_000\PycharmProjects\Pacman\Game.py", line 65, in draw
   self.player.draw()
   File "C:\Users\fotio_000\PycharmProjects\Pacman\Player.py", line 18, in draw
   if (tup[0] == self.x) and (tup[1] == self.y):
TypeError: 'int' object is not subscriptable

为什么要为对象播放器设置多个位置？

int压缩器self.pos是元组列表：

self.pos = [(self.x, self.y)]

但是当您在movement中进行更改时，它是一个单独的位置，列表中存储了2个坐标：

self.pos = [self.x, self.y]

这就是导致错误的原因。将后者更改为self.pos = [(self.x, self.y)]可以解决此问题，但是...

由于您想在位置（self.x，self.y处绘制一个圆，因此无需将列表中的位置与（self.x，{{ 1}}）。请注意，{self.y，self.x）始终存储在列表中，所以为什么要尝试验证呢？
只需在（self.y，self.x）处画一个圆。例如：

self.y

“ int”对象不可下标。元组错误
