Tkinter Label
Tkinter Label belongs to Tkinter desktop UI. Create Tk(), add this widget, pack or grid it, then mainloop() — without mainloop the window never appears.
Tkinter Label — output: Tk() then Label(text='Hello Asha') then pack → mainloop. Run real Tkinter on your laptop to open the window.
Trap for Tkinter Label: writing command=fn() with brackets. That calls the function immediately. Pass the function name: command=fn.
Widget job + pack + mainloop. One sentence each.
