I thought the opposite of “functional” was “procedural”, not “imperative”.
The opposite to the latter is “declarative”. But (nearly) all procedural
languages also have declarative constructs, not just imperative ones
(certainly Python does).
Python has only two: 'global' and now 'nonlocal'.
There are also two meta-declarations: the coding cookie (which would/will go
away in an entirely unicode world) and future imports (which are effectively
temporarily gone in 3.x until needed again).
Newbies sometimes trip over def and class being imperative (executable)
statments rather than declarations.
Er, declarative programming has nothing to do with variable declarations.

I found it hard to get much from the vague description. I will leave it
to Lawrence to list what *he* thinks are 'declarative constructs' in Python.
