Given the following definition of classes, I am getting an unexpected error of :
TypeError: __init__() missing 2 required keyword-only arguments: 'idcode' and 'tag' On the call to create a GedcomHead in the call to GedcomHead() in Gedcom0Tag.add() Code: class GedcomTag: """Represents a Level of a Gedcom file""" def __init__(self, parent: 'GedcomTag', level: int, tag: str, payload: Optional[str]): pass class Gedcom0Tag(GedcomTag): """Represents a Level 0 Tag of a GEDCOM file""" def __init__(self, *, parent, idcode: Optional[str], tag: str): super().__init__(parent=parent, level=0, tag=tag, payload=idcode) @classmethod def add(cls, *, parent, tag: str, payload: str, level=0): """Add Tag based on text""" if tag == 'HEAD': data = GedcomHead(parent=parent) elif tag == 'TRLR': data = GedcomTRLR(parent=parent) else: data = Gedcom0Tag(idcode=tag, tag=payload, parent=parent) return data class GedcomHead(Gedcom0Tag): """GEDCOM 0 HEAD tag""" def ___init___(self, *, parent): super().__init__(parent=parent, idcode=None, tag="HEAD") Gedcom0Tag.add(parent, 'Head', '') Note: GedcomHead.__init__() doesn't have these parameters, somehow it seems be requiring the parameters for the __init__ call of the base class too, even though there is a call to it through the super().__init__() Is this expected? Can derived classes not provide values for parameters to construct the base classes? Is there something funny because I am making the call from a member of that base class? -- Richard Damon -- https://mail.python.org/mailman/listinfo/python-list
