Stuck, Reindeer spotter


I have been spending a good amount on this level but I still can’t figure it out. Help will be greatly appreciated
Thank you

# This array contains the positions of the pens that we want to put the reindeer in.
penPositions = [ {'x':20,'y':24}, {'x':28,'y':24}, {'x':36,'y':24}, {'x':44,'y':24}, {'x':52,'y':24} ]

# This array is used to track which reindeer (if any) is in each pen.
penOccupants = [ 'empty', 'empty', 'empty', 'empty', 'empty' ]

# And this array contains our reindeer.
friends = hero.findFriends()

# Figure out which reindeer are already in their pens.
for deerIndex in range(len(friends)):
    reindeer = friends[deerIndex]

# Go through each position and see if it matches the reindeer's position.
for penIndex in range(len(penPositions)):
    penPos = penPositions[penIndex]
    if penPos.x == reindeer.pos.x and penPos.y == reindeer.pos.y:
        # Put the reindeer's ID in the penOccupants array in slot penIndex.
        # break out of the inner loop here to avoid confusion.

# Tell Merek what's in each pen.
for occIndex in range(len(penOccupants)):
    penOccupant = penOccupants[occIndex]
    speech = "pen " + occIndex + " is " + penOccupant
    # Tell Merek the pen index and the occupant.
    # Say something like "Pen 2 is empty" or "Pen 3 is Dasher"
