Yes, that's pretty much it.  If you can point your finger at the thing
and say that it produces a value, it's an expression.

See:

    https://docs.python.org/2/reference/expressions.html

Technically, the only things that count as expressions have to fit the
shape of something described in that documentation link.



Your question about assignment being an expression or not is something
you can find out by seeing where "Assignment statements" show in:

Good luck!
