Your prompt
Convert the code below to Python, written idiomatically for that language — not a line-by-line transliteration of the original's structure.
After the converted code, list every behaviour difference this introduces or that the target language forces: numeric precision and overflow handling, how errors or exceptions propagate compared to the original, differences in default mutability or concurrency model, and standard-library edge cases such as string encoding or integer division. If part of the original logic has no clean equivalent in Python, say so and explain the closest approximation rather than silently changing what it does.

Why this prompt works
- →Asking for idiomatic code instead of a transliteration prevents JavaScript-shaped Python (or the reverse) — code that runs but reads as a translation rather than native code.
- →Requiring an explicit list of behaviour differences surfaces exactly the bugs silent conversions cause: a float that overflows differently, an error swallowed instead of thrown, division that truncates where the original didn't.
- →Flagging logic with no clean equivalent stops the conversion from quietly reinterpreting a language-specific idiom into something that merely looks similar but behaves differently.
