我正在使用 Python 和 tkinter 开发 Python 文本编辑器。但是我在更改文本小部件的字体颜色时遇到了一些问题。
我刚开始写。
到那时才5分钟。

这是editor.py

##imports
from tkinter import Tk,Text,BOTH,font
from font import fontify

##When the text gets edited
def Keyboardpress(key):
    editarea_text = editArea.get("1.0","end")
    ##Calling the fontify function for doing some chill!
    fontify(editArea,editarea_text)

##Creating Window
editor = Tk()

##resizing editor
editor.geometry("400x400")

##creating a font
myFont = font.Font(family='Courier',size = 24,weight = "normal")

##Here goes the ui
editArea = Text(editor,bg="#333",fg="#eee",height = 400,width = 400,font = myFont)
editArea.bind('<key>',print())
editArea.pack(fill = BOTH)

##binding Button press with editor
editor.bind( '<Key>', lambda i : Keyboardpress(i))

##Excecuting Window
editor.mainloop()

**这是 font.py ** 
keywords = ["False","await","else","import","pass","None","break","except","in","raise","True","class","def"]#and so on

def fontify(self,self_text):
    self.tag_remove('keyword', '1.0', "end")

    for word in keywords:
        idx = '1.0'
        while idx:
            idx = self.search(word, idx, nocase=0, stopindex="end")
            if idx:
                lastidx = '%s+%dc' % (idx, len(word))
                self.tag_add('keyword', idx, lastidx)
                idx = lastidx

    self.tag_config('keyword', foreground='deeppink')

运行这给了我想要的输出

但是如何去除这些不想要的颜色

这对我有帮助
idx = self.search(word, idx,forwards=0,backwards=0,stopindex="end")

argumentforwards 表示在搜索中接受向前的字符。论点恰恰相反
。backwards
让他们假帮助我
