Well, the title says the most. Just searching for a new one to learn. Mine is in fact, Python 3.7. I like Python 3.7, because it runs on like everything, even on my small raspi zero.
Mh I should add that I, in this moment, I speak Python, R, in advanced 8/10 levels of skill, HTML in beginner level, as I do in CSS and C++. JS in mid levels of skill
Beginners can just jump into it. It's so flexible. The package manage is one of the largest out there. You can use it to develop front-end web apps, back-end servers, mobile apps, make games, desktop apps, and more! The ecosystem is huge - sometimes it's hard to keep up, but there is so much useful tooling. Ex. you can augment your experience with babel and transpile from the coolest features - that are hot off the press from the spec!
