Time Any Function

Medium ⏱ 12 min 45% acceptance ★★★★☆ 4.2

Write timed(func) decorating a function so it returns a tuple (result, elapsed_seconds) measured with time.perf_counter around the call. Discussion point: changing a function's return shape is invasive — real profilers log instead — but it makes the mechanics visible here.

Examples

Example 1

Input

@timed applied to slow_add; slow_add(2, 3)

Output

(5, 0.0001...)

Explanation

The wrapper measured and bundled the timing.

Constraints

Use perf_counter, not time.time.
Preserve the wrapped name with wraps.
