You could add an attribute to each embedded object that provides a reference back to the container object. All in all, this design has a kind of smell to it. Would it not be better to ask the container class for information about the children, rather than the other way around? If a piece of code holds a reference to the child object then it must also by definition hold a reference to the container object, so why can't it ask the container object directly? -- https://mail.python.org/mailman/listinfo/python-list
