Tkinter GUI窗口Blan

Question

我决定试着写一个程序，根据人体脂肪测试仪的测量结果来计算你的体脂百分比。几年前，我为一个朋友创建了一个excel电子表格，这样他就可以计算客户的体脂百分比。我觉得为他设计一个程序会很酷，也会给我一些练习的机会。在

当我运行这个程序时，它似乎没有任何问题，除了Tkinter窗口出现完全空白。有人能找出我在代码中做错了什么吗？在

另外，如果我能做到这一点，我是否可以创建一个可执行文件给我的朋友，或者用某种方法让桌面运行一个脚本来运行python代码？他将使用Mac，所以在python已经安装的情况下，我想可能有某种方法可以运行终端脚本，但我不知道该怎么做。在

如有任何帮助，我们将不胜感激，代码如下：

您忘了对所有帧使用pack()。在

要在窗口中放置框架，请执行以下操作：

self.gender_frame.pack()
self.tricep_frame.pack()
self.chest_frame.pack()
self.abdominal_frame.pack()
self.suprailiac_frame.pack()
self.thigh_frame.pack()
self.button_frame.pack()
