我创建了一些入口小部件，供用户输入不同团队的分数。我想知道，如何将它们分配到特定的列表中，并将这些点相加以打印结果。。。我下面的代码显示了我尝试过的内容，但它不起作用，我收到了一个错误：ValueError: invalid literal for int() with base 10: ''
此外，如果我将删除求和函数，则数字不会出现在列表中。有人能给我解释一下如何解决这个问题吗？我的代码：

AS编写代码时，它会执行以下操作：当它运行时，它试图获取Entry对象上的值，但什么都没有，所以这就是错误，你试图转换为int a"。正确的做法是：

有一些事情需要更改，您可以通过注释看到它们，您正在使用列表，因此，为了使用sum((函数，您需要.append()列表上的值，并且每次调用函数时都使用pointsTeam1 = []重置列表使用self.跟踪属性并获取新函数的值get_values()最后，我做了一个函数来检查插入的值是否是数值，并将其转换为int，否则返回0，您可以引发错误或显示一些消息
我希望我对有所帮助
