Hi, I'm trying to package spades[1] and found the following code inside an __init__.py file:
... class YAMLObjectMetaclass(type): """ The metaclass for YAMLObject. """ def __init__(cls, name, bases, kwds): super(YAMLObjectMetaclass, cls).__init__(name, bases, kwds) if 'yaml_tag' in kwds and kwds['yaml_tag'] is not None: cls.yaml_loader.add_constructor(cls.yaml_tag, cls.from_yaml) cls.yaml_dumper.add_representer(cls, cls.to_yaml) class YAMLObject(metaclass=YAMLObjectMetaclass): """ An object that can dump itself to a YAML stream and load itself from a YAML stream. """ __slots__ = () # no direct instantiation, so allow immutable subclasses yaml_loader = Loader yaml_dumper = Dumper ... which ends up in File "/usr/share/spades/pyyaml3/__init__.py", line 284 class YAMLObject(metaclass=YAMLObjectMetaclass): ^ SyntaxError: invalid syntax I'm not a very skilled Python coder but IMHO the critical line should be replaced by class YAMLObject(YAMLObjectMetaclass): Is this correct? Do you have any clue whether this is some old syntax or what sensible hint I might give to upstream? Thanks for your patience Andreas.
