tkinter label is not showing properly in python

Look at the codes!

root = Tk()
frame = Frame(root)
labelText = StringVar()
label = Label(frame, textvariable=labelText)
labelText.set("Connecting to the server...")



def welcome_note():
    time.sleep(5)
    labelText.set("Welcome!")

welcome_note()

label.pack()
frame.pack()

root.mainloop()

When executing the code it should be as "connecting server" then after 5 seconds it should show "welcome"

But it is executing only "welcome" after 5 seconds...

Here this should fix your problem. It happened because your label didn't know about the updated information. So adding these lines will show the changes.

Use this link for more information.

from tkinter import *
import time
root = Tk()
frame = Frame(root)

labelText = StringVar()

labelText.set("Connecting to the server...")

label = Label(frame, textvariable=labelText)


label.pack() # ADD THIS
frame.pack() # ADD THIS
label.update() # ADD THIS



def welcome_note():
    time.sleep(5)
    labelText.set("Welcome!")
    label.pack()
    frame.pack()

welcome_note()



root.mainloop()

Use the method after to call welcome_note after 5 seconds

def welcome_note():
    labelText.set("Welcome!")

root = Tk()
frame = Frame(root)
labelText = StringVar()
label = Label(frame, textvariable=labelText)
labelText.set("Connecting to the server...")
label.pack()
frame.pack()
# Calls welcome_note after 5 seconds
root.after(5000, welcome_note)
root.mainloop()
