Also, does it start with 0 or 1 (or -3023 for that matter)? As a programmer you would assume of course it starts at 0, but since this thread talks about "non-programmer" academic types I think it's worth mentioning. What if I want a range of 1-15, or 20-50, can I still use range()? I can't tell from the Python example but I can tell exactly what I would need to change with the Swift one to make it work exactly how I'd want.

Very true, and this is especially important in data science, where the majority of languages, other than Python, are 1 indexed (Matlab, Julia, R, FØRTRAN).
