Oh, cool. But then the semantics are clear: if using [a:b:c] syntax, the replaced slice has to be of same lenght. Makes sense - and in that case, I'd prefer c==1 not to be special cased - for the sake of a more clearly defined behaviour. Regards, Diez -- http://mail.python.org/mailman/listinfo/python-list
