I favor Python for data science and machine learning tasks. Last year I did a project with ML written in Python running on an Azure cloud. Input/output was via REST methods to hide the interior details of the ML application.
I was on a technical challenge team that was given a database of all satellite orbits and all ship voyages over a 20 year time span. The task was to identify every ship that managed any segment of its voyage outside the view foot print of any satellites. It was a very intensive bit of processing. We successfully delivered the answer and won the proposal.
