a, b = b, a + b — Tuple unpacking (`a, b = b, a + b`). Tension: Tuple unpacking (`a, b = b, a + b`) evaluates the right side fully before assignment, so both values update simultaneously without a temp variable. Outcome: This is the most Pythonic and memory-efficient approach for sequential Fibonacci generation.
