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ive在10个星期内自己学到的东西的结晶.我的程序在没有GUI的情况下在程序级别上运行良好.我的程序是一个典型的拼字游戏求解器.我刚与tkinter在一起度过了可怕的时光.我需要将输入从主模块输入到主模块,然后将结果输入到列表框.我什至放弃了从主要类传递参数的过程,因此我将机架和结果设置为全局变量.我知道这对某人帮助可能是很麻烦的,但是我在总决赛之前完成此工作的任何帮助将不胜感激.先感谢您.
#only reason these are global is because im having trouble with tkinter and
#passing the proper parameters to the main module
global results

解决方法:
尽管我删除了滚动条(我想您也会想出如何添加滚动条的方法),但我还是完全重写了您的代码,使其更具Python风格,并且更易于阅读和编写.但是,我尝试尽可能地坚持您的代码.
我想它现在正在工作：
这是我使用的dictionary.dat：
beast
lemon
ape
apple
sea
pea
orange
bat
这是代码本身：
# Import python modules
import tkinter
import tkinter.messagebox
from collections import Counter
# Module level constants
SCORES = {'A': 1, 'C': 3, 'B': 3, 'E': 1, 'D': 2, 'G': 2, 'F': 4, 'I': 1,
'H': 4, 'K': 5, 'J': 8, 'M': 3, 'L': 1, 'O': 1, 'N': 1, 'Q': 10,
'P': 3, 'S': 1, 'R': 1, 'U': 1, 'T': 1, 'W': 4, 'V': 4, 'Y': 4,
'X': 8, 'Z': 10}

# Check length of data
if len(rack) <= 8:
return self.find_valid_words(rack)
self.error()
