I have making a program.

It needs show some colorful words use this: \033[1mabc

I tryed this command and it failed:

import tkinter as tk
root=tk.Tk()
text=tk.Text(root)
text.insert('end', '\033[1mabc')

It shows a tofu and [1mabc. But I want get a red abc. How can I get it?

P.S. It will do like this:

import socket
import tkinter as tk
root=tk.Tk()

// connect the port use socket 'socket'

text=tk.Text(root)
text.insert('end', socket.read(1024))

And in the port of the computer:


//socket connected front is 'socket'

// when connect
import subprocess
command=subprocess.Popen(socket.read(1024), shell=True, output=subprocess.PIPE, error=subprocess.INPUT)
socket.send(command.output.read(1024))

// stop the 'command' Popen

You can't, not with tkinter.Text. \033[1m is an ANSI escape sequence, specifically the Select Graphics Rendition sequence, to change how a terminal should color the following text.

tkinter.Text does not interpret those sequences at all.

Here's an example of a function that supports a semblance of rich text in a tkinter.Text widget using tags:

import tkinter as tk


def set_text_with_attributes(text_widget, texts_and_attributes):
    i_start = text_widget.index(tk.INSERT)
    for i, (text, attributes) in enumerate(texts_and_attributes):
        text_widget.insert(tk.END, text)
        i_end = text_widget.index(tk.INSERT)
        tag_name = f'tag{i}'
        text_widget.tag_add(tag_name, i_start, i_end)
        text_widget.tag_config(tag_name, **attributes)
        i_start = i_end


root = tk.Tk()
text = tk.Text(root)

set_text_with_attributes(text, [
    ("Hello, ", {}),
    ("World!\n", {"foreground": "red"}),
    ("Once upon a time, ", {"foreground": "black"}),
    ("there was a ", {"foreground": "blue"}),
    ("fox", {"background": "orange"}),
    (" who jumped over ", {}),
    ("the ", {"foreground": "green"}),
    ("lazy ", {"background": "yellow"}),
    ("dog", {"foreground": "purple"}),
])

text.pack()

root.mainloop()

This shows

As for newbie. Just 15 lines try this.

import tkinter as tk

def onclick():
   pass

root = tk.Tk()
text = tk.Text(root)
text.insert(tk.INSERT, "It shows a tofu and [1mabc But I want get a red abc. How can I get it")
text.pack()

text.tag_add("here", "1.0", "1.4")
text.tag_add("start", "1.47", "1.51")
#text.tag_config("start", background="yellow", foreground="red")
text.tag_config("start", foreground="red")
root.mainloop()

If you want background and foreground. Comment in line13 and comment out line 14.

for intermediate levels. If you want, select any word or multiple words and highlight and then clear it. I added two buttons.

import tkinter as tk
from tkinter.font import Font


class Pad(tk.Frame):
    def __init__(self, parent, *args, **kwargs):
        tk.Frame.__init__(self, parent, *args, **kwargs)

        self.toolbar = tk.Frame(self, bg="#eee")
        self.toolbar.pack(side="top", fill="x")
        
        self.bold_btn = tk.Button(self.toolbar,
                                          text="Highlight",
                      command=self.highlight_text)
        
        self.bold_btn.pack(side="left")

        self.clear_btn = tk.Button(self.toolbar,
                                           text="Clear",
                       command=self.clear)
        
        self.clear_btn.pack(side="left")

        self.text = tk.Text(self)
        self.text.insert("end", "It shows a tofu and [1mabc. But I want get a red abc. How can I get i")
        self.text.focus()
        self.text.pack(fill="both", expand=True)
        
        self.text.tag_configure("start", foreground="red")
        #self.text.tag_configure("start", background="black", foreground="red")

    def highlight_text(self):   
        try:
            self.text.tag_add("start", "sel.first", "sel.last")     
        except tk.TclError:
            pass


    def clear(self):
        self.text.tag_remove("start", "1.0", 'end')


def demo():
    root = tk.Tk()
    Pad(root).pack(expand=1, fill="both")
    root.mainloop()


if __name__ == "__main__":
    demo()

Output:

Btw, if you want background and foreground. Comment out line 29 and comment in line 30.
