That is precisely the point. If it was:
assignment_stmt ::= (target_list "=") expression_list |
(target_list "=") assignment_stmt
(i.e. removing the '+' which your eyes jumped over)
then the actual assignments would have to apply right to left with each
assignment giving the result for the next one.
But since it is:
assignment_stmt ::= (target_list "=")+ expression_list
the repeated target lists may be expected, and are indeed defined, to
assign left to right.
