如果没有实际测试过代码，我很确定问题是你的 PhotoImage 对象被垃圾收集。出于某种奇怪的原因，只需将它们传递给 canvas.create_image 就不会阻止这种情况。尝试让它们全球：

Without having actually tested your code, I'm pretty sure the problem is that your PhotoImage objects are being garbage-collected when you exit the method. For some weird reason, just passing them to canvas.create_image won't prevent this. Try to make them global:

global game
game = PhotoImage(file=imagelist[randomimage])
images = canvas.create_image(30, 65, image = game, anchor = NW)

更多指示：

• 条件如 event.x> 853和event.x< 957 可以写成 853< event.x< 957


• 您可以将 imagelist 定义为 [％d.gif ％（i + 1）for i in range（50）]


• 方法后的一个以毫秒为单位的时间，所以我想这应该是之后（1000，...）


• 在它的当前状态，按下时== 8：循环似乎没有多大意义，因为按下设置为


• 最后，我建议定义一个自定义的类GameFrame（Frame）并将所有这些内容放在该课程中，而不是将所有内容全局;在这种情况下，您可以使用 self 关键字将 PhotoImage 绑定到 Frame 以防止垃圾收集

• conditions like event.x >853 and event.x <957 can be written as 853 < event.x < 957
• you can define your imagelist as ["%d.gif" % (i+1) for i in range(50)]
• the after method takes a time in milliseconds, so I guess this should be after(1000, ...)
• in it's current state, the while pressed == 8: loop seems not to make much sense, since pressed is set to '' after one iteration anyway
• finally, I'd recommend defining a custom class GameFrame(Frame) and putting all this stuff in that class, instead of making everything global; in this case, you can use the self keyword to bind your PhotoImage to the Frame to prevent it from being garbage-collected
