Hi, I have seen a recipe which allows auto creation of missing values for dictionaries. However this recipe is not working for all.
class AutoValueDict(dict): def __makeitem__(self, key): return self.setdefault(key, {}) def __getitem__(self, key): return self.get(key, self.__makeitem__(key)) I would like to have a dictionary which ensures dictionaries as values except when I'm assigning another: dict["abc"]["xyz"]["123"]["456"] = 123 How can I do this without many "if" and "else"? best regards Thomas -- http://mail.python.org/mailman/listinfo/python-list
