First off, loop: is not an useable function anymore. Second, the #8th line of your code has indented twice.

accidentally posted the wrong code whoops

All of your strategies cannot be defined as a string, and you did not mention them in your code. You have to define your strategy, like “griffin-rider”

Here is an example:

def griffin_rider():
    griffin = hero.findByType("griffin-rider")
    for griffin in griffins:
        friendEnemy = griffin.findNearestEnemy()
        if friendEnemy:
            # And on with your code

while True:
    griffin_rider()
    friends = hero.findFriends() # Define again, griffin cannot find enemies alone
    for friend in friends:
        # Your action, remember to attack as well
        # Tip, look for the best target, what is next to a fangrider?

alright ill try changing that

You defined chooseStrategy twice, try deleting one to avoid errors.
You also gotta write some code, instead of passing.

The return string is to help you define the next usage, but you should NOT use it itself, you still have to use the defination.
