Reject Negative Arguments at the Door

Medium ⏱ 12 min 63% acceptance ★★★★☆ 4.4

Write positive_args(func) — a decorator raising ValueError if ANY positional argument is a negative number, before the wrapped function runs. Decorating deposit(account_id, amount) then centralizes validation that would otherwise repeat in every money function.

Examples

Example 1

Input

decorated_deposit(1, 500)

Output

normal result

Explanation

All positives pass through.

Example 2

Input

decorated_deposit(1, -500)

Output

ValueError

Explanation

The wrapper rejected before execution.

Constraints

Check only positional args that are int/float.
Raise before calling func.
