By that standard nothing is. At some point if you are using a programming language you are going to have to RTFM. None of things you cherry-picked would be used by a novice either.
Every example you gave are what I call are "Ronsil" (https://en.wikipedia.org/wiki/Does_exactly_what_it_says_on_t...).
Even the pickle.dumps() example is obvious when you read the description for the module and works exactly the same to json.dumps(), which works similarly to dumps() methods and terminology in other programming languages.
I feel like I am repeating myself.
> A lot of languages work for RAD including Clojure, C#, and JavaScript. This is nothing special about Python.
Nonsense. None of those I would say are RAD. JavaScript literally has no standard lib and requires node/npm these days and that can be a complete rigmarole in itself. C# these relies heavily on DI. I have no idea about Clojure so won't comment.
All the RAD stuff in C# and JS is heavily reliant on third party scripts and templates, that have all sorts of annoying quirks and bloat your codebase. That isn't the case with Python at all
