How do I add a time delay to a tkinter Label?

August 18, 2022

I’m creating a Treasure Island type game with tkinter and I’m trying to add a delay before the label "line1" appears in the GUI, I’ve tried the after function but I don’t know how I would properly implement it. Anyway here’s the code:

import time
import tkinter
window = tkinter.Tk()

window.title("Treasure Island")
window.geometry("500x500")

logo = tkinter.Label(window, text='''
          |                   |                  |                     |
 _________|________________.=""_;=.______________|_____________________|_______
|                   |  ,-"_,=""     `"=.|                  |
|___________________|__"=._o`"-._        `"=.______________|___________________
          |                `"=._o`"=._      _`"=._                     |
 _________|_____________________:=._o "=._."_.-="'"=.__________________|_______

          |           |o`"=._` , "` `; .". ,  "-._"-._; ;              |

logo.pack()
logo.config(font=('length', 15))

line1 = tkinter.Label(window, text="Welcome to Treasure Island,\n"
                                   "Your goal is to find the buried Treasure!")
line1.pack()
line1.config(font=('length', 15))

window.mainloop()

>Solution :

for delay, you can use after method that take two arg
first arg time by millisecond and second arg is a function
more detail see

def callback():
  line1 = tkinter.Label(window, text="Welcome to Treasure Island,\n"
                                   "Your goal is to find the buried Treasure!")
  line1.pack()
  line1.config(font=('length', 15))


window.after(3000, callback) #time by milisecond
