Heavens no!!! Using setattr and getattr is *less* idiomatic. > Is there something you can with them that you can't by obj.field > reference? Absolutely. Consider: class Foo(object): pass foo = Foo() setattr(foo, "x y", 1) print getattr(foo, "x y") That's probably an abuse of setattr/getattr, but there are times where you might not know the name of the attribute until runtime, so you can't write foo.attr since you don't know what to write in place of attr. That's where setattr and getattr (as well as delattr and hasattr) come into play. -- Steven -- http://mail.python.org/mailman/listinfo/python-list
