I wrote the below code

    if ((represent is None) and (search_field is None)):
        fieldmethod = Field.Method(name, f)
    else:
        class Handler(object, ):
            def __init__(self, method, row):
                self.method = method
                self.row = row
            def __call__(self, *args, **kwargs):
                return self.method(self.row, *args, **kwargs)
        if (represent is not None):
            if hasattr(represent, 'bulk'):
                Handler.represent = represent
            else:
                Handler.represent = staticmethod(represent)
        if (search_field is not None):
            Handler.search_field = search_field
        fieldmethod = Field.Method(name, f, handler=Handler)
    return fieldmethod

What's a good function header?

Here's a good function header?
