python字母图案编程 python编写字母标红

python gui tkinter菜鸟编程 练习 ch17_22 在编写文字程序时，如果想要让程序更完整可以设计拼写检查功能，其实在本节并没有介绍Text控件的新功能，这算是一个应用的专题程序。
程序实例ch17_22.py：设计一个小字典myDict.txt，然后将Text控件的每个单词与字典的单词做比较，如果有不符的单词则用红色显示此单词。
这个程序另外两个功能按钮，“拼写检查”按钮可以执行拼写检查，“清除”按钮可以将红色显示的字改为正常显示。

原代码存在一个问题，只能检测第一次错误的单词，第二次出现错误的单词则不能检测

迭代后的程序，可以将所有不匹配的单词标红。

if(word not in dicts and word.lower() not in dicts):
            print("error:",word)
            pos = text.search(word,start,END)
            text.tag_add("spellErr",pos,"%s+%dc"%(pos,len(word)))
            start = "%s+%dc"%(pos,len(word))  #更新搜索寻起始位置
            # pos = "%s+%dc"%(pos,len(word))

主要修改点
