Your mission

Implement prune_negatives, which removes the negative numbers from the list it receives, so that the caller's own list holds what is left.

See it in action

(prune_negatives(nums := [4, -2, 0, -7, 9]), nums)

(None, [4, 0, 9])

(prune_negatives(nums := [-1, -1]), nums)

(None, [])

prune_negatives([3, 1])

None

Your checklist

• values holds zero or more ints, of any sign and size.
• Remove from values every number below 0, and nothing else.
• The numbers left keep their original order.
• The result is in the list the caller passed: after the call, the caller's values holds it.
• Return None.
