title: TypeError: must be str or None, not Frame
body: <p>Using an OOP approach to developing a tkinter program for the first time based on the sentdex tkinter series. I honestly have no idea what the error here means.</p>
  
  <p>The error directs me to:</p>
  
  <pre><code>  File "C:\Users\Ash\Dropbox\Programming\Python\WorldManager PY\WorldManager.py", line 59, in __init__
  tk.Tk.__init__(self, *args, **kwargs)
  File "C:\Python34\lib\tkinter\__init__.py", line 1867, in __init__
  self.tk = _tkinter.create(screenName, baseName, className, interactive, wantobjects, useTk, sync, use)
  TypeError: must be str or None, not Frame
  </code></pre>
  
  <p>The code I've used is <a href="http://pastebin.com/kCGGrpkr" rel="nofollow">here</a></p>
  
  <p>EDIT: While the code says the line is 59, the error is on line 46. I took out a few comments from above the code when I pastebinned it. </p>
