Here's a good function header given the following:
I wrote the below code

    def initialize(self, *args, **kwargs):
        cls = type(self)
        for (k, v) in kwargs.items():
            if hasattr(cls, k):
                attr = getattr(cls, k)
                if isinstance(attr, InstrumentedAttribute):
                    column = attr.property.columns[0]
                    if isinstance(column.type, String):
                        if (not isinstance(v, six.text_type)):
                            v = six.text_type(v)
                        if (column.type.length and (column.type.length < len(v))):
                            raise exception.StringLengthExceeded(string=v, type=k, length=column.type.length)
        init(self, *args, **kwargs)
    return initialize

What's a good function header?
