Well, for what it's worth, I certainly also "grew up" with 0-based indexing (actually, literally grew up since I was a kid when I learned Pascal). I'm just saying that 1-based has really grown on me and that I find myself thinking about avoiding off-by-one errors far less often when using 1-based indexing. There are other times when I really wish I was using 0-based indexing. However, I find that that latter are more often times when I'm doing libraryish internals code, whereas the former are more common when I'm doing high level userish code.

My experience is the exact opposite.

I find 1-based indexing to be weird/illogical and prone to off-by-1 errors.

Inclusive/exclusive ranges as in Python along with 0-based indexing means the likelihood of any off-by-1 is negligible...
