Tkinter Label — Python Technical Interview Questions & Answers

Tkinter Label

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.

Technical Interview Tip: Widget job + pack + mainloop. One sentence each.
