Hi! I thought that maybe dict could accept several mappings as positional arguments, like this:
class Dict4(dict): > def __init__(self, *args, **kwargs): > if len(args) > 1: > if not all([isinstance(arg, dict) for arg in args]): > raise TypeError('Dict4 expected instances of dict since > multiple positional arguments were passed') > > temp = args[0].copy() > > for arg in args[1:]: > temp.update(arg) > > super().__init__(temp, **kwargs) > else: > super().__init__(*args, **kwargs) > AFAIK, this wouldn't create compatibility problems, since you can't pass two positional arguments now anyways. It would be useful to solve the "sum/union dicts" discussion, for example: requests.get(url, params=dict(params, {'foo': bar}) Whar are your thoughts?
