Python Tkinter单选按钮程序调试

Question

本质上，该程序是一组单选按钮，当用户单击提交按钮时，该程序应返回与用户所做的选择字符串匹配的答案。 我已经让它在很大程度上起作用了，但最终做出的决定仍然是错误的。 让我知道我是否可以回答更多问题。

Answer 1

您应该在比较Intvar实例时使用get方法，并且您的tkMessageBox.showinfo(title, message)函数需要两个参数，而不是只传递标题而没有消息，因此将代码更改为如下所示：

if q1.get() == 1 and q2.get() == 1 and q3.get() == 2 and q4.get() == 2 and  q5.get() == 1 and q6.get() == 2 and q7.get() == 2 and q8.get() == 2 and q9.get() == 2 :
    tkMessageBox.showinfo('Info','You should use the t-test!')

并且也不要使用sys.exit()退出你的程序它会导致你的程序没有响应而是使用root.destroy()

希望您的消息框现在应该按预期工作！

可选：使用tkMessageBox.showerror(title, message)显示错误消息

Answer 2

您应该允许未找到的条件。 列表还可以更容易地理解恕我直言。 以下内容应该是不言自明的。 它只测试前两个条件，第三个选项可以轻松测试代码，并添加了打印语句进行测试。 你可以从那里扩展。 此外，使用列表或函数将大大减少“标签、按钮和按钮”代码的数量。
