In "6.11. Conditional expressions" the first line reads: """ conditional_expression ::= or_test ["if" or_test "else" expression] """ I think this should be """ conditional_expression ::= expression ["if" or_test "else" expression] """ and maybe the third line, """ expression_nocond ::= or_test | lambda_expr_nocond """ should also replace "or_test" by somethings else? A truly conditionless expression or something in parentheses if containing a condition? -Alexander
