It also has the nice feature of being good at multiple things. If you get a model running in Python, and decide you want to be able to run the code via an API, put it behind Flask and ta-da!, now it's a network service.

It's not the best way to write analysis code, and it's not the best way to write a web service, but it's probably the best way to write analysis code that runs on a web service.

I picked web services as a random example, not one I'm particularly passionate about. But as a general trend, if you want to combine 2 unrelated domains, Python probably has you covered better or more easily than just about any other language.
