The Fastest Way to Loop in Python: Using Built‑in Functions and Math Instead of While/For Loops

This article demonstrates that in Python, plain while and for loops are significantly slower than using built‑in functions like sum or applying a direct mathematical formula, because the former execute extra Python‑level boundary checks and increments, making the latter the most efficient looping alternatives.
