Python Recursion through objects and child objects, Print child depth numbers

Question

I have a simple class with an attribute that can contain a list of objects of the same class

class BoxItem:
  def __init__(self, name, **kw):
      self.name         


        

Answer 1

You have two options:

1. Keep track of the additional information as an additional parameter in your recursion, e.g. myRecursiveFunction(..., ancestry=[])
2. Have each BoxItem keep track of its parent, whenever it is embedded in a BoxItem (in the __init__ constructor, set child.parent = self for each child). This is bad if you plan to have a BoxItem in more than one box.
