tkinter和拼字游戏求解器问题

标签： python class tkinter python-3.3

我必须学习python 3.3.3的逻辑和设计课程。我对编程非常陌生，下面的代码是我在10周内自学的结果。我的程序在程序级别上运行良好，没有GUI。我的程序是一个典型的拼字游戏解算器。我和tkinter度过了一段可怕的时光。我需要从输入到主模块的输入，并将结果输入到列表框。我甚至放弃了从他主要的类中传递参数，所以我将机架和结果设置为全局变量。我明白，对于有人提供帮助可能会有太多的麻烦，但是在决赛之前我会非常感激地帮助我完成任务。提前谢谢你。

#only reason these are global is because im having trouble with tkinter and
#passing the proper parameters to the main module

虽然我删除了滚动条（我想你会弄清楚如何添加它）我完全重写了你的代码，更加pythonic，更容易阅读和写。但是我尽可能地坚持你的代码。

我猜它现在正在运作：

以下是我使用的dictionary.dat：

apple
sea
pea
orange
bat

以下是代码本身：

# Module level constants

          'H': 4, 'K': 5, 'J': 8, 'M': 3, 'L': 1, 'O': 1, 'N': 1, 'Q': 10,
