Grim Determination Help

Hi guys, I am messing up where my paladins are supposed to heal lowestFriend, if their health is below 200, however I don’t know how to use the return from the previous function in another, please help. My code is below.

# Your goal is to protect Reynaldo

# Find the paladin with the lowest health.
def lowestHealthPaladin():
    lowestHealth = 99999
    lowestFriend = None
    friends = hero.findFriends()
    for friend in friends:
        #if friend.type != "paladin":
        #    continue
        if friend.health < lowestHealth and friend.health < friend.maxHealth:
            lowestHealth = friend.health
            lowestFriend = friend

    return lowestFriend

def commandPaladin(paladin):
    nearestEnemy = paladin.findNearest(paladin.findEnemies())
    lowestFriend = lowestHealthPaladin()
    if paladin.pos.x < 70:
        hero.command(paladin, "move", {"x":paladin.pos.x + 2})
    if lowestFriend:
        if paladin.canCast("heal") and lowestFriend.health < 200:
            hero.command(paladin, "cast", "heal", lowestFriend)
    if paladin.health < 200:
        hero.command(paladin, "shield")
    elif nearestEnemy:
        hero.command(paladin, "attack", nearestEnemy)
        pass    
    # Heal the paladin with the lowest health using lowestHealthPaladin()
    # You can use paladin.canCast("heal") and command(paladin, "cast", "heal", target)
    # Paladins can also shield: command(paladin, "shield")
    # And don't forget, they can attack, too!
def commandPeasant(peasant):
    nearestItem = peasant.findNearest(peasant.findItems())
    if nearestItem:
        hero.command(peasant, "move", nearestItem.pos)
        pass

def commandGriffin(griffin):
    enemy = griffin.findNearest(griffin.findEnemies())
    if enemy:
        hero.command(griffin, "attack", enemy)
        pass    

def summonGriffin():
    if hero.gold >= hero.costOf("griffin-rider"):
        hero.summon("griffin-rider")
    else:    
        pass 

def summonPeasant():
    if hero.gold >= hero.costOf("peasant"):
        hero.summon("peasant")
    else:    
        pass     

def commandFriends():
    # Command your friends.
    friends = hero.findFriends()
    for friend in friends:
        if friend.type == "peasant":
            commandPeasant(friend)
            pass
        elif friend.type == "griffin-rider":
            commandGriffin(friend)
            pass
        elif friend.type == "paladin":
            commandPaladin(friend)
#summonPeasant()
while True:
    commandFriends()
    summonGriffin()

    # Summon griffin riders!

@cipherbear The function hero.findFriends() returns other allied troops besides the paladins. So you will want to make sure that you are checking for that as well. If the ally is not a paladin you wouldn’t want to return it.
