title: Python Tkinter listbox text edit in GUI
body: <p>Is there a way to edit a listbox item instead deleting it?</p>
  <p>I am using a tkinter GUI with a listbox. Now my listbox could contain for example 10 items. If I would like to change the text of one item, is there a way to do it?</p>
  <p>I know I can create a button to delete a single item, but is there any way to also jut edit an item?</p>
