If Python is a "batteries included" language, then Wolfram Language might be a "nuclear reactor included" language. Its functionality covers a broad range of domains, and keeps growing. The principle behind much of it is "maximum automation", so you have so-called "hyperfunctions" to, for example, build a classifier using machine learning. You just give it the example data, and it'll by default pick the method, etc. for you and perform the training. You can still go in and control the options if needed.

The language itself has its quirks, like any 30 year old language would, but you can do a lot with a little if you know what you're doing. It's similar to Lisp in that way.

The downside is that once you need to go beyond the "standard library" things are a lot more sparse, but they've been working to make it easier to get 3rd party functionality.

It's the kind of language that if it was free 15 years ago would probably be all over the place today.
