getters and setters

[Skaperen]

my new class has set_opts() and get_opts().  set_opts() works from named options.  get_opts() returns a dict with the options.  an additional feature: set_opts() returns a dict of unrecognized options.  this new class has 8 options (there are not setters or getters for individual options because of so many).

The problem with getters/setters is not code verbosity. It is that they allow inconsistent states. If you rename some "Marmaduke Skaperen" to "Alexandre-Benoit Ofnuts" with setters on first name and last name, your object can temporarily be set to "Marmaduke Ofnuts" or "Alexandre-Benoit Skaperen".

but ... should i change this part of my code?

    def get_opts(self):
        return {
            'gutter':  self.gutter,
            'width':   self.width,
            'height':  self.height,
            'height2': self.height2,
            'top':     self.top,
            'left':    self.left,
            'right':   self.right,
            'bottom':  self.bottom,
        }

    def set_opts(self,**opts):
        for o in option_names_all:
            if o in opts:
                v = opts.pop(o)
                if v != None:
                    setattr(self,'_'+o,v)
        return opts
