I used default as a keyward arg name indicating the presence of a callable. I probably should have called it defaultfunc or something. x = d.get('a', f) # --> default value is f x = d.get('a', defaultfunc=f) # --> default value is result of f() . -- http://mail.python.org/mailman/listinfo/python-list
