title: tkinter display values in a popup
body: <p>I'm trying to make some basic GUI and I'm having some trouble with this code:</p>
  
  <pre><code>with open(project_dir + 'logs/wash.log') as f:
      for line in f.readlines():
          if not line.startswith('BSSID       ') and \
             not line.startswith('------------'):
              print(line)
  </code></pre>
  
  <p>At this point of the application I have the tkinter root already opened in the background and a terminal opened too, I would like to open a new tkinter window in which display the line printed above, I suppose adding a label in the window for each line that I need to display.</p>
  
  <p>I tried tk.Toplevel() but I don't know how to make the new window in which display the strings.</p>
  
  <p>My problem is I am trying to create a new window and print the strings there, I have tried tk.Toplevel() but I don't know how to make the new window in which to display the strings</p>
