title: running __init__ inside its own definition
body: <p>I'm currently learning tkinter from sentdex's tutorial and to me it seems that I'm writing to run <code>__init__</code> in its own definition, what does a line like that mean? Is it tKinter's <code>__init__</code> function?</p>
  
  <pre><code>class seaOfBTCapp(tk.Tk):
  
      def __init__(self,*args,**kwargs)
           tk.Tk.__init__(self,*args,**kwargs)
  </code></pre>
