How to change the title bar in Tkinter?

Tkinter initially sets a default title bar for every application. We can update or replace the Title Bar of the Tkinter application by configuring the title("Enter any Title") method. For a particular application, let us see how we can change the title of a Tkinter application that calculates the square of a number.

Example

#Import the required Libraries from tkinter import * from tkinter import ttk import math #Create an instance of Tkinter frame win = Tk() #Set the geometry of tkinter frame win.geometry("750x270") #Set the Title of Tkinter window win.title("Square Calculator") def find_square():    no= int(entry.get())    Label(win, text=no*no).pack() #Create an entry widget to accept user input entry= Entry(win, width=40) entry.pack(ipadx= 20,pady=20) #Create a button to calculate the number ttk.Button(win, text= "Calculate", command= find_square).pack() win.mainloop()

Output

The above program calculates the square of the given number in the Entry widget. Thus, the program window Title has been renamed to "Square Calculator".
