But they did mention Hy, a lisp dialect written in Python. I find this hy-larious.
It certainly is one way to learn Python better as you'll be working, indirectly, in its abstract syntax tree. You can do this in plain Python but the ast module is woefully under-documented and rarely used.
I recently used the ast module to find imports to see which lines in "pip freeze" are actually necessary for any given file/directory. It was pretty neat, and I hope I have a reason to use it again.
How important is metaprogramming to Python? Frankly, in my 16+ years as Python developer, I have never seen anything that can be remotely described as metaprogramming in Python, except in academic code and experimental GitHub projects.
They are a form of metaprogramming, but other than decorators, Python generally discourages other kinds of metaprogramming. Metaclasses are reserved for very specific use-cases, and monkey patching or re-opening class definitions are almost always considered anti-patterns.
That's an oops on my part. Chalk it up to a baby who likes to wake up at 4:45am and a toddler who wakes up at 7.
frozenset is just a built-in immutable set type with a nice hashing algorithm for the kinds of workloads you'd expect. It's defined in Objects/setobject.c and is a nice read.
I was just rambling and I've used frozenset in metaprogramming code when constructing classes via decorators to implement Lattice types with decorated monotone/morphism methods.
- It is really easy to download, install, and be coding in 5 minutes.
- There's a nice GUI IDE, if that's your cup of tea. (Also I maintain racket-mode for Emacs.)
- It is "batteries included" (maybe not compared to Python (!), but definitely compared to most Schemes).
- You can write everything from command-line programs that launch quickly, to GUI apps, to web apps.
And particularly why I mention it here:
- You can explore many approaches mentioned in the OP: functional, gradual typing, object-oriented, lazy evaluation, datalog, and more. (Ultimately, Racket is "a programming-language programming language". Although you can ignore that level of abstraction and simply use it as a very nice lisp.)
BUT SQL is so old /sarcasm. It drives me nuts when people who should know better can't just jump on notepad and write a simple query in SQL. They spend half an hour looking how to do what a basic 101 SQL code could solve in 30 seconds.
In the section "Array-oriented data processing", Fortran should be included. Fortran 95 (and the earlier Fortran 90) has array operations, and Fortran 2003 supports object-oriented programming. The gfortran compiler, which is part of gcc, implements all of Fortran 95 and almost all of Fortran 2003.
Fortran is also one the primary languages in which statistical algorithms have been coded.
This is from a Coursera Course that is not being offered right now. It covers a lot of different languages but the Racket and ML parts are a great starting point.
I took this course last year and loved it. As a self taught developer as well, these videos really helped me understand some concepts that I still hadn't wrapped my head around yet.

The ABC module, collections, frozenset. Basically anywhere we add custom types or generate new classes to instantiate.

Sorry for the confusion!

I think part of the point was to support other Open Source languages.

Is this true?

Here is what got me off the ground. The first unit is learning ML and the second unit was Racket. https://www.youtube.com/user/afigfigueira/playlists?shelf_id...

I liked this book - http://www.amazon.com/Realm-Racket-Learn-Program-Game-ebook/...
If that is too simple there always is http://www.amazon.com/How-Design-Programs-Introduction-Progr...
I prefer seeing people code and talk about it so the videos are great.
I like too the fair descriptions of the major Python's alternative programming approaches and languages, even if this list is incomplete.
