I guess I fail the first test, and I don't actually understand why. When I follow the prints, it all looks pretty logical to me, and I don't get where exactly it went wrong. My code is attached if you want to take a look. But most probably the logic is what I did not understand.

The test:

unit_1 = Warrior()
unit_2 = Vampire()
weapon_1 = Weapon(-10, 5, 0, 40, 0)
weapon_2 = Sword() # h +5 a +2
unit_1.equip_weapon(weapon_1)
unit_2.equip_weapon(weapon_2)
print(fight(unit_1, unit_2))
assert (fight(unit_1, unit_2)) == True

Outputs:

- Warrior equipped weapon <__main__.Weapon object at 0x7faa62e91c90> now health is 40 and max health is 40
- Vampire equipped weapon <__main__.Sword object at 0x7faa62e91cc0> now health is 55 and max health is 55
