How do I change the Tkinter default title in the OS bar?

The Tkinter application window has many components: window size, title, navbar, menubar-component, etc. To configure the window attributes or properties, we can use the Window Manager toolkit defined in Tcl/Tk.

To run the Window Manager attributes, use the command 'wm' with other keywords. The title of the window can be configured by using wm_title("title") or title("title") method.

Example

# Import the required libraries
from tkinter import *

# Create an instance of tkinter frame or window
win=Tk()

# Set the size of the window
win.geometry("700x350")

# Change the title of the window
win.wm_title("My Window")

Label(win, text="Hello, Welcome to Tutorialspoint...", font=('Calibri 24')).pack()

win.mainloop()

Output

If we run the above code, it will display a window with a title "My Window".
