functools.wraps preserves metadata

Question

Accepted Answer

Applying `@wraps(func)` to the inner wrapper copies the original function's `__name__`, `__doc__`, `__qualname__`, and other attributes onto `wrapper`. So even though `compute` now points to `wrapper`, `compute.__name__` reports `'compute'`. Without `@wraps`, you'd get `'wrapper'` instead - which breaks logging, introspection, and test frameworks that rely on function names.
