Numerical computation is generally done on scripting platforms - Matlab for instance. After a few different options such as Octave, numerical computation in the free software space coalesced around Python. The Python ecosystem - it's change and release processes (PIPs etc) - thorough API documentation - make for a good target language, over other languages that simply do not have that infrastructure. I don't know what the state of Ruby documentation is these days for instance, but back in the day, it was simply incomplete.
