Pygame：添加到列表的顺序混乱

Question

我制作了一个循环，以特定顺序将图片、x 坐标和 y 坐标添加到列表中。但是，我的程序进一步出错，并且发现问题出在将这些元素添加到列表中的顺序。谁能告诉我为什么会这样？

代码：

zero = pygame.image.load("0.png").convert_alpha()

one = pygame.image.load("1.png").convert_alpha()

two = pygame.image.load("2.png").convert_alpha()

three = pygame.image.load("3.png").convert_alpha()

four = pygame.image.load("4.png").convert_alpha()

five = pygame.image.load("5.png").convert_alpha()

six = pygame.image.load("6.png").convert_alpha()

seven = pygame.image.load("7.png").convert_alpha()

eight = pygame.image.load("8.png").convert_alpha()

nine = pygame.image.load("9.png").convert_alpha()

numList = [zero,one,two,three,four,five,six,seven,eight,nine]

blitList = []

i=0

while i<10:

    i=i+1

    numX = random.randint(20,1320)

    numY = random.randint(20,700)

    number = random.choice(numList)

    blitList.append(number)

    blitList.append(numX)

    blitList.append(numY)

列表打印时间：

[<Surface(70x69x32 SW)>, 506, 110, <Surface(69x69x32 SW)>, 1177, 559, <Surface(69x69x32 SW)>, 524, 467, <Surface(69x69x32 SW)>, 263, 232, 630, <Surface(69x69x32 SW)>, 551, <Surface(69x69x32 SW)>, 58, 123, <Surface(69x69x32 SW)>, 1157, 520, <Surface(69x69x32 SW)>, 772, 640, <Surface(69x69x32 SW)>, 178, 522]

顺序应该是'[surface], x-value, y-value...'等等，但是当我打印它的时候，每次都改变顺序混乱的顺序。（在这种情况下是第五个）

我对此很陌生，但也许您在循环或其他事情中两次选择了同一张图片，这就是搞砸了。如果你在循环外洗牌 numlist 并从洗牌的 numlist 追加会有帮助。该循环距离选取所有对象也短 1 个。

    blitList.append(number)

    blitList.append(numX)

    blitList.append(numY)

    i=i+1
