            self.text.insert(END,text)
        self.text1.delete(0.0, END)
        self.text1.insert(END,proc.communicate()[0])



    def file_save(self):
        """get a filename and save the text in the editor widget"""
        # default extension is optional, here will add .txt if missing
        fout = asksaveasfile(mode='w', defaultextension=".txt")
        text2save = str(self.text.get(0.0,END))
        fout.write(text2save)
        fout.close()

    def do_exit(self):
        root.destroy()



root = Tk()
root.title("Named Entity Recognizer (TR)")
app = App(root)
root.mainloop()

First i show the original text and second i show the edited text which found ner types. I know it works with tag configure but how can i add the words inside the brackets. Thanks for helping.

text.tag_config("[Person: ??]", background="yellow", foreground="red")

Copied this from the interwebs somewhere

def color_text(edit, tag, word, fg_color='black', bg_color='white'):
    # add a space to the end of the word
    word = word + " "
    edit.insert('end', word)
    end_index = edit.index('end')
    begin_index = "%s-%sc" % (end_index, len(word) + 1)
    edit.tag_add(tag, begin_index, end_index)
    edit.tag_config(tag, foreground=fg_color, background=bg_color)


# pick word to be colored
myword1 = 'Jack'
myword2 = 'Jill'
# create a list of unique tags
tags = ["tg" + str(k) for k in range(len(word_list))]
for ix, word in enumerate(word_list):
    # word[:len(myword)] for word ending with a punctuation mark
    if word[:len(myword1)] == myword1:
        color_text(edit, tags[ix], word, 'blue')
    elif word[:len(myword2)] == myword2:
        color_text(edit, tags[ix], word, 'red', 'yellow')
    else:
        color_text(edit, tags[ix], word)

What you do here is create a Tkinter Canvas. I'm not sure of the exact syntax in python 2 because I use 3, but that will only result in minor changes:

from Tkinter import *
root = Tk()

c = Canvas(root, width=500, height=500, bg='red') #change the color at bg
c.pack()
c.mainloop()

You can change the Canvas color with a variable according to your output. Where it says bg='red' , that's where you change the color. Please tell me if I've got python 2 incorrect syntax, hope this helps!
