The cultural shock when a Python programmer encounters MATLAB's 1-based indexing is like discovering your favorite coffee shop now exclusively serves decaf.
In Python, arrays start at index 0 like any civilized programming language. Then MATLAB comes along with its "indexes start at 1" heresy, triggering an existential crisis in developers who've built their entire identity around zero-based indexing.
The transition is basically the five stages of grief, except you get stuck in the anger phase indefinitely. And that little MATLAB mascot's smug face isn't helping matters.
