I hope that's now what it says about slices -- that was meant for dict displays. For slices it should be symmetrical. In this case I would remove the spaces around the +, but it's okay to add spaces around the : too. It does look odd to have an operator that binds tighter (the +) surrounded by spaces while the operator that binds less tight (:) is not. (And in this context, : should be considered an operator.) -- --Guido van Rossum (python.org/~guido) _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
