Tkinter Button — Python Technical Interview Questions & Answers

Tkinter Button

Tkinter Button

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