The test in Python (mention the language next time, please) is like this:

test.assert_equals(hero(0, 1), False)

And it is fine. Not a kata issue.

There are issues wtih the test. All of the test, but the one where the bullets is 0 and dragons is 1. When I attempt the code, it passes, but due to the test with (bullets=0, dragons=1) are coming up True, but it should be coming up False. Please check to see if the test needs to be fixed. I think if all of the tests on the attempt are passing, but only one test is the hold up, there might be a logic issue with the test.
