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

    def getter(self):
        return self.headers.get(header, None)
    def setter(self, value):
        self.headers[header] = value
    return property(getter, setter, doc=('Retrieve    and    set    the    %s    header' % header))

What's a good function header?
