I think you're a bit confused.

Procedural refers to the way you program. It ranks up there with object oriented and functional programming.

Scripting refers to the environment in which it is run, and scripting languages in particular require what is called an "interpreter." In otherwords, Python (like Perl), is a run-time "compiled" code. You can produce standalone executables from Python (and Perl, etc), but they are not the same sort of executables produced by gcc and C programs.

You need the ability run the source as a script, which requires an interpreter. IIRC, there are also distinctions that have to do with weak typing and the ability for various to be converted into different types on the fly. These days, the waters are very muddy.

There are other languages that are held up as the epitome of pure OOP - and I don't think Python is high on that list. I would say that is is better at OOP than Perl, which requires some fakery to use its natural features to emulate OOP functionality. OOP is overrated anyway :)

I am happy that so many people love Python, but like any language, it is not all it's cracked up to be.
