The conditional expression documentation says: conditional_expression ::= or_test ["if" or_test "else" expression] I've stared at this and the PEP, and I''m pretty sure that the first or_test should be an expression, not an or_test. In an expression like "x if C else y", x and y are expressions and C is the or_test. The documentation in question is at http://docs.python.org/reference/expressions.html#conditional-expressions Ken

Hi Ken, Even if its name may be unfortunate, "or_test" is the correct symbol in this case; it means that you can write ``a or b if c or d else e`` (course, this is close to unreadable). regards, Georg -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.15 (GNU/Linux) iEYEARECAAYFAkwTKD4ACgkQN9GcIYhpnLCY9gCfeFvGgvPi9F1lbGB0lCI0B3OZ HE8AoJDzL8ODbJgvMlKYRwcK9Ed9E08I =/1zl -----END PGP SIGNATURE-----
