title: Why do we store methods in a variable when using Tkinter in python?
body: <p>I just started learning Tkinter and when thing that really stood out was </p>
  
  <pre><code>win=tkinter.Tk()
  </code></pre>
  
  <p>I mean from what it looks win is basically a reference for the main window we created but  this is the first time I have seen something like this since tk() is a method and not a class . I know that everything is an object in python eh but I am kinda confused , help me senpais ....</p>
