It doesn't. __defaults__ was added in 3.x (and it is documented). Prior to that, in 2.x, there was func_defaults. Jython is not in 3.x yet, so you should not expect 3.x features there. As for func_defaults, its there and supported as documented: Jython 2.5.1+ (Release_2_5_1:exported, Mar 21 2010, 01:00:17) [Java HotSpot(TM) Server VM (Sun Microsystems Inc.)] on java1.6.0_22 Type "help", "copyright", "credits" or "license" for more information. >>> def test(a=123): ... return a ... >>> test() 123 >>> test.func_defaults (123,) >>> test.func_defaults = (456,) >>> test() 456 -- With best regards, Daniel Kluev -- http://mail.python.org/mailman/listinfo/python-list
