注：食品的数值单位为KJs。到目前为止，我有所有的值，但它们只是放在那里，例如11801800，但没有加起来。我使用了r.get（）+v.get（），但它们实际上并没有将值相加。它们确实相加了。您的问题是r.get（）返回的是字符串，而不是整数。先换算，然后求和
int(r.get()) + int(v.get())
您好，我尝试了您的方法，但这是我得到的错误：只能将str（而不是“int”）连接到str。有解决方法吗？谢谢感谢你的帮助，我的总数是：def total（）：total=int（v.get（））+int（r.get（））+int（q.get（））f4.configure（text=“你当前的总数是：”+total+“KJs”）@Cheezdoodle你把所有的
。getstr（）v.get（）
