title: When to use pack or grid layouts in tkinter?
body: <p>Are there any best practice tips regarding when one should use pack vs. grid for their layouts?</p>
  
  <p>From what I've been reading via google, the concencus seems to be that grid can handle any pack scenario but not vice-versa.</p>
  
  <p>To start the conversation, it appears that one use case that favors grid vs. pack is when one wants to show/hide widgets.</p>
