title: Italicize tkinter label text on focus
body: <p>I have a tkinter label </p>
  
  <p><code>back_button = Label(self.about_frame, text = "Back", bg="black", fg="white", font=("Silkscreen", 18))</code></p>
  
  <p>and I want to have the text's font change from regular to italic when a user hovers over the label with their mouse. How should I go about implementing this? Thanks!</p>
