Question

此代码适用于琐事游戏，每当有人提出正确的问题时，每个问题都会获得一定数量的积分。我不知道在每个正确的答案后如何让代码在一起添加点数。每当我尝试不同的东西时，我总会收到此错误消息。

Answer 1

你将这些点作为字符串获取，并且需要在之前将它们转换为int ，并且最好使用它进行任何计算：

points = int(next_line(the_file))
next_block中的
应该可以解决问题。此外，您没有将积分添加到乐谱中，而是替换它。

total = sum(points + points) score = total

应该是

score += points

将'points'添加到'score'。

TypeError：+：'int'和'str'的不支持的操作数类型
