It's also worth mentioning that Python ships with a nice "batteries included" type setup, where installing the basic CPython interpreter and the bundled libraries give you a quite nice collection of tools for common computing tasks (e.g. making HTTP requests).

In contrast, JavaScript does not have a "standard" implementation and doesn't ship with any libraries. Sure, there's Node.js and probably others too.

Once you have a serious project, where you have dependencies and build systems and source control, it's not a very big issue to get install a few libs. But for small projects, Python's batteries come in handy. And some of those small projects turn into big projects.

What comes to Python 2 vs. Python 3, I feel it's a "can't make an omelette without breaking eggs" kind of issue. Unfortunately many people are running business critical applications with Python 2 and are not willing to put in the effort to migrate their code to Python 3. This "don't fix it if it ain't broken" attitude has slowed down Python 3 adoption.

I'm not sure that Python 3 adoption is "slow", per se. We're about halfway through the original adoption timeline.
