Question

这是我的整个代码段，但是在玩游戏后我很难使比分显示出来。分数已正确添加到文件中，但是当我打印分数时，即使我已经添加了新分数也没有出现。如何修复我的代码以使其显示？我是编码新手，所以对您有所帮助。我认为这是一个容易解决的错误，但我不知道如何解决。谢谢！

您永远不会更新scoreslist使其包含sum（通过append对其进行编辑或再次从文件中读取scoreslist）。添加将sum添加到scoreslist的行：

add_file_contents(scoreslist_path, '\n' + str(sum))
scoresline.append(sum)

数字正在添加到文件中，但在打印时不会显示
