Inner Classes: How can I get the outer-class object at construction time?

Question

Consider the following Python (runs in 2.x or 3.x):

class Outer(object):
  pass

  class Inner(object):
    def __init__(self):
      print(\"Inner.self\", s         


        

Answer 1

Can't be done. But with a bit of redesign:

class Outer(object):
  pass

  class _Inner(object):
    def __init__(self, outobj):
      self.outobj = outobj

  def Inner(self):
    return self._Inner(self)

o = Outer()
i = o.Inner()

print o, i.outobj
