I actually prefer the 0 indexing of python. Systems code (c/c++ etc.) already uses 0 based indexing. So it is nice that when you do data science the convention stays the same.
Does it actually matter at this point? I write off by one errors all the time in JavaScript and I usually spot them immediately. I’ve written Julia and R in the past and I found it really easy to switch between contexts, and if I forget, the errors are such that it takes only a few seconds to spot and fix them.
