How Can I Make Text Blinking On Canvas ? I Tried Creating A Variable flag And :

You can use .after(...) to call function() periodically and then toggle the state of the canvas text item (which should be created outside function()) between "normal" and "hidden" to simulate blinking effect:

import tkinter as tk
from PIL import ImageTk

def function(show=False):
    btn.config(state="disabled")
    canvas.itemconfig(text, state="normal" if show else "hidden")
    canvas.after(200, function, not show) # change 200 to other value to adjust the blinking speed

win = tk.Tk()

canvas = tk.Canvas(win)
canvas.pack()

img = ImageTk.PhotoImage(file=r"images.png")
canvas.create_image(0, 0, anchor=tk.NW, image=img)

text = canvas.create_text(134, 26, fill="black", font="Times 26 bold", text="Blinking...")

btn = tk.Button(win, text="Click Me To Blink...", command=function)
btn.pack()

win.mainloop()
