When almost any statistical work is done in python, we use numpy arrays, sometimes via the pandas or statsmodels etc. libraries. We seldom use native python types.
I run a company which develops medical devices, many of which combine mechanical, electronic and software engineering. It's well known (and a running joke) that software engineers from non-medical fields think it is acceptable to ship their product with serious defects. It takes a long time and a lot of training to get them up to the level that we need, more so than for mechies and sparkies.
