title: Emulate waiting for input() in Tkinter
body: <p>I am trying to recreate a command-line application into a desktop one using Tkinter. I cannot seem to figure out how to recreate the <strong>input()</strong> function - waiting for input and pressing Enter to confirm. Has anyone had a similar issue?</p>
  <p>I have looked into <strong>button_pressed</strong> in Tkinter. Is there a better alternative?</p>
