Challenge 149 - Calculating Damage

Create a function that takes damage and speed (attacks per second) and returns the amount of damage after a given time.

Examples

calculate_damage(40, 5, "second") ➞ 200

calculate_damage(100, 1, "minute") ➞ 6000

calculate_damage(2, 100, "hour") ➞ 720000

Notes

• Return "invalid" if damage or speed is negative.

    def test_3(self):

    def test_4(self):
        self.assertEqual(600, calculate_damage(20, 0.5, "minute"))

    def test_5(self):
        self.assertEqual(2880000, calculate_damage(2, 400, "hour"))

    def test_6(self):
        self.assertEqual("invalid", calculate_damage(-23, 20, "second"))

    def test_7(self):
        self.assertEqual("invalid", calculate_damage(-23, -5, "second"))

    def test_8(self):
        self.assertEqual("invalid", calculate_damage(20, -492321, "hour"))
