'Used when an object is in a list of ambiguous objects as an
additional information tag.
For instance, if you had potions which could have varying
levels of liquid left in them, you might want to display how
many drinks are left in each when selecting which to drop, but
not in your normal inventory listing.
Args:
looker (TypedObject): The object or player that is looking
at/getting information for this object.
Returns:
info (str): A string with disambiguating information,
conventionally with a leading space.'

def get_extra_info(self, looker, **kwargs):

    if (self.location == looker):
        return '    (carried)'
    return ''
