There is great momentum in a community that already knows a language and wants to *do work* with that. (i.e. that is not primarily programming, but merely *using* programming to achieve some other goal.)
So, those people will reach for what they already know, which in this case is #Python; and if it is good enough, then other niche special-purpose tools don't even get investigated.
A special property of Python is impressive support for so many use cases; people try it, it just works!
