CodeWars Python Challenge — Opposite Number in Under 3 Minutes ⚡

Today I solved the “Opposite Number” kata on CodeWars using Python 🐍 This challenge was extremely simple: given a number, return its opposite. Examples: 1 → -1 -7 → 7 0 → 0 I solved it by simply multiplying the number by `-1`. At first I wondered if Python had a special built-in function for this… but actually the mathematical approach is already the cleanest and simplest solution.
