i making metaclass customize __new__ method customize how new class created according provided values in kwargs . makes more sense in example: class foometa(type): def __new__(cls, name, bases, kwargs): # kwargs... # example: if 'foo' in kwargs: kwargs.update({ 'fooattr': 'foovalue' }) return super(foometa, cls).__new__(cls, name, bases, kwargs) my problem how can make compatible both python 2 , 3. six great compatibility library not solve problem. use as: class fooclass(six.with_metaclass(foometa, foobase)): pass this not work because 6 creates new base class using given metaclass. below six's code ( link ) (as of 1.3): def with_metaclass(meta, base=object): return meta("newbase", (base,), {}) as result, __new__ method called without kwargs hence "breaking" function. question how can accomplish behavior want without breaking compatibil...

is there way in pygame detect if rect inside mask? i know there rect in rect collision , collidepoint (point in rect collision) there way detect if rect inside mask? thanks i don't believe there function supplied pygame that. challenging, because of "shapeless" possibilities of mask. 1 possibility might work first list of bounding rects of mask (a list of rects "contain" of points of mask) , check if rect inside of these rects: bounding_rects = mask.get_bounding_rects() b_rect in bounding_rects: if b_rect.contains(test_rect): print "rect inside mask" of course solution, if rect inside mask, not inside 1 particular bounding rect, test fail. here's idea of how might handle that, tradeoff of little bit of lost precision: bounding_rects = mask.get_bounding_rects() mask_rect = bounding_rects[0].unionall(bounding_rects) if mask_rect.contains(test_rect): print "rect inside mask" this solution unions of...

suppose have this: network = { post: function(t) { console.log(t); } protocol: { init: function() { /* network.post("init") */ } } } the commented part, how allow network.protocol.init function call network.post through sort of relative link? how can network.protocol find networks variables? thanks. :) this limitation of object literal syntax; can't it. your best option reference network via property on protocol object, , add after declaring object via object literal syntax; network = { post: function(t) { console.log(t); } protocol: { init: function() { this.network.post("init") } } } network.protocol.network = network; ... works because existance of network property deferred until execution of init itself.
