When i run my code it shows this error.

```python
def findWeakestEnemy():
    enemies = hero.findEnemies()
    weakest = None
    leastHealth = 99999
    enemyIndex = 0
    # Loop through enemies:
    while enemyIndex < len(enemies):
        # If an enemy's health is less than leastHealth:
        enemy = enemies[enemyIndex]
        if enemy.health < leastHealth:
            # Make it the weakest 
            enemy[enemyIndex] = weakest
            # and set leastHealth to its health.
            leastHealth = enemy[enemyIndex].health
            pass
        enemyIndex += 1
        pass
    return weakest

while True:
    # Find the weakest enemy with the function:
    findWeakestEnemy()
    # If the weakest enemy here:
    if weakest:
        # Attack it!
        hero.attack(weakest)
    pass

```

You do not need to put `enemy[enemyIndex]` when you redefine `weakest`, just `enemy`. Same deal with the lowest health.  
Also it is `weakest = enemy`, not `enemy = weakest`.  
Happy to help 🙂

Make sure you assign findWeakestEnemy to a variable; For example:

weakestEnemy = findWeakestEnemy()

if weakestEnemy:
