I've inferred that, in Python, all assignments are by definition statements, rather than expressions, so they can't be arbitrarily substituted in for expressions. It's interesting to see the two ways in which people seem to go from C's middle ground of expressions and statements; some languages go to making statements into expressions, others go for even further narrowing the set of "expressions". I'm not yet sure which I prefer; both have some appeal in avoiding some of the occasional-complexity that can make C hard for people to learn. (Meaning, complexity which is only sometimes at issue, so you have to know about it, but you can't just use it all the time, so you can't assume it's how things work.) -s -- Copyright 2010, all wrongs reversed.
