Python is easy to get started with, but once a project grows to any meaningful size, I would rather have a compiler which is giving me more correctness guarantees than Python is capable of.
IMO Swift strikes the best balance between strictness and productivity of any language I've worked with.

boy do I have a continent full of python developers to introduce you to... “python - by any means necessary” is their motto.
But in all seriousness, there are a lot of people (where I work) who started with python and have been daily driving it for so long that any other language is too tedious to get started with. Even if it means writing unreadable, hacky python, python still wins out for them.
I suspect there are a lot of similar people in data science.
