title: default argument in bound function
body: <p>I'm developing a python script which sends text data to a zebra labelprinter.
  There's one bound function called "zebra_line" and you have to fill in x, y, text and font variables.</p>
  
  <pre><code>    zebra_line = "^FO{x},{y}^A0,N,{font}^FH^FD{text}^FS".format
  
      template = "^XA\n"
      template += "^CI28\n"
      template += zebra_line(x=30,y=350, text="Test", font=35)
      template += zebra_line(x=30,y=700, text="Test", font=35)
  
  send_to_printer(template)
  </code></pre>
  
  <p>This works nice but my problem is with the font argument. I don't want to pass it with every line as it is mostly the same.</p>
  
  <p>So...is it possible to use default arguments in bound functions in Python?</p>
