Let me try a less subjective description. Things like None, 2.3, 'foo', True are values or "expressions"; I'm not certain exactly what the term for these is in Python's grammar, but I basically mean something that can be on the RHS of an assignment.. However, something like 'for' or 'if' is part of some other grammatical construct, generally a statement or operator of some kind, so I tend to think of those differently. -- mithrandi, i Ainil en-Balandor, a faer Ambar
