function overloading

[Simon Burton]

I just wrote the following rediculous code.
What do people do when they need to overload like this?

# PIL stuff

class Im:
  def __init__(self,x,xx=None):
    if xx is not None:
      w,h = x,xx
      im = Image.new("I",(w,h))
    elif type(x)==str:
      filename = x
      im = Image.open(filename)
    else:
      im = x
    self.im = im
