Being compatible with different flavours is nice :)

Here is a parameter wrapper to use parameters additionally as attributes than as dictionary elements:

from Parameters import Parameters as pdict

class Parameters(object):
    def __init__(self):
        self.dict = pdict() # include dictionary

    def __getattr__(self, name):
        if name in ("read", "write", "get") : # local attributes
            return getattr(self.dict, name)
        
        if name == "dict" :
            return self.__dict__[name]

        return self.dict.get(name)
    
    def __setattr__(self, name, value):
        if name == "dict" : # local attribute
            self.__dict__[name] = value
        else:
            self.dict[name] = value

if __name__ == "__main__" :    
    p = Parameters()
    p.read("../AIR/LuxPose/data/dataOut.bbml")
    camera = p.get("Camera")
    film = p.get("Film")
    renderer = p.get("Renderer")
    
    print "CAMERA as dict:", p.get("Camera", "No Camera found")
    print "FILM as dict:", p.get("Film", "No Film found")
    print "RENDERER as dict:", p.get("Renderer", "No Renderer Found")
    print
    print "Camera as attribute:", p.CaMeRa # attributes ignore upper-/lowercase
    print "Film as attribute:", p.Film
    print "RENDERER as attribute:", p.renderer
    print
    print 'camera.has_key() reports "cameratype" is %sincluded in p.camera' % ("not ","")[p.camera.has_key("cameratype")]
    print
    print "Camera contains this attributes/keys", p.camera.keys()
    
    p.write("../AIR/LuxPose/data/dataOut-copy.bbml")
