title: vertical padding between buttons in a column
body: <p>When I pad the widgets they all just move together on the same frame in 1 big block. I need to be able to separate them and add the padding between each widget on the same frame. This is part of my code I tried:</p>
  
  <pre><code>def CreateDisplay(self):
  
      self.mainwindow = tk.Tk()
      self.mainwindow.geometry("800x600")
      self.mainwindow.wm_title(self.constants.NAME)
      self.mainwindow.resizable(width=False, height=False)
  
      self.frame_main = tk.Frame(master = self.mainwindow)
      self.frame_title = tk.Frame(master = self.frame_main)
      self.frame_test = tk.Frame(master = self.frame_main)
      self.frame_recentscore = tk.Frame(master = self.frame_main)
      self.frame_help = tk.Frame(master = self.frame_main)
      self.frame_exit = tk.Frame(master = self.frame_main)
  
      self.frame_main.pack(pady=15)
      self.frame_title.pack(anchor="c")
      self.frame_test.pack(pady=15)
      self.frame_recentscore.pack(pady=15)
      self.frame_help.pack(pady=15)
      self.frame_exit.pack(pady=15)
  
      self.label_title = tk.Label(self.frame_title, font=("purisa", 20), text="Business Studies Finance Revison:")
  
      self.label_title.pack()
  
      self.button_test = tk.Button(self.mainwindow, padx=54, pady=3, font=("Purisa",15), text="Take a Test", command=self.parent.test).pack()
      self.button_recentscore = tk.Button(self.mainwindow, font=("Purisa",15), text="View My Recent Scores", command=self.parent.recentscores).pack()
      self.button_help = tk.Button(self.mainwindow, padx=88, pady=3, font=("Purisa",15), text="Help", command=self.parent.help_mainwindow).pack()
      self.button_exit = tk.Button(self.mainwindow, padx=91, pady=3, font=("Purisa",15), text="Exit", command=self.parent.Exit).pack()
  </code></pre>
  
  <p>Everything works other than the padding between the widgets.
  I have all the running files of this in a separate file as its a big project.
  The padding in the widgets definition is just to shape them not move them on the frame. How can we add vertical padding between the buttons in a column?</p>
