Polymorphism using constructors

[K Viltersten]

I'm writing a class for rational numbers
and besides the most obvious constructor

  def __init__ (self, nomin, denom):

i also wish to have two supporting ones

  def __init__ (self, integ):
    self.__init__ (integ, 1)
  def __init__ (self):
    self.__init__ (0, 1)

but for some reason (not known to me at
this point) i get errors. My suspicion 
is that it's a syntax issue.

Suggestions?
