Yes, this is Python (take note of the main category of this post ;)

You may do similar kinds of things in R as well, however if you are just starting to get acquainted with the field and have the luxury of choosing your first language arbitrarily, I would recommend considering Python.

The Python community is larger and many of the state of the art machine learning methods (which I do plan to eventually reach with this series of posts, in particular) are somewhat easier to work with in Python, in my opinion.
