soi am doing reindeer Tender but thir is a strang error  
my code:

```python
# This is the array of pen positions
penPositions = [{"x":20,"y":24}, {"x":28,"y":24}, {"x":36,"y":24}, {"x":44,"y":24}, {"x":52,"y":24}]

# Use this array to keep track of each pen's reindeer.
penOccupants = [None, None, None, None, None,]

# 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]
    
    # For each position check if it matches a reindeer.
    for penIndex in range(len(penPositions)):
        penPos = penPositions[penIndex]
        
        if penPos.x == reindeer.pos.x and penPos.y == reindeer.pos.y:
            # Put the reindeer in occupants at penIndex
            penOccupants[penIndex] = reindeer.id
            # Remove the reindeer from the friends array.
            friends[penIndex] = None
            # break out of the inner loop here:
            break
            pass

# Assign the remaining reindeer to new positions.
for deerIndex in range(len(friends)):
    # If the reindeer is null, use continue:
    reindeer = friends[deerIndex]
    if friends[deerIndex] == None:
        continue
    
    # Look for the first pen with nothing.
    for occIndex in range(len(penOccupants)):
        # If there is nothing, the pen is open:
        if not penOccupants[occIndex]:
            # Put the reindeer in the occupants array.
            penOccupants[occIndex] = reindeer.id
            # Command the reindeer to move to the pen.
            hero.say(reindeer.id + penPositions[occIndex])
            # break out early so we don't reassign:
            break
            pass

```

the error:

i know you’re not supposed to do this, but will it work if you check for the reindeer before checking it’s pos.x and pos.y?

try checking for the reindeer again, and instead of doing `hero.say(reindeer.id + penPositions[occIndex])`, actually command them like a soldier with `hero.command()`

my new code:

        if penPos.x == reindeer.pos.x and penPos.y == reindeer.pos.y:
            # Put the reindeer in occupants at penIndex
            penOccupants[penIndex] = reindeer.id
            # Remove the reindeer from the friends array.
            friends[penIndex] = None
            # break out of the inner loop here:
            break
            pass

# Assign the remaining reindeer to new positions.
for deerIndex in range(len(friends)):
    # If the reindeer is null, use continue:

    if friends[deerIndex] == None:
        continue
    
    # Look for the first pen with nothing.
    for occIndex in range(len(penOccupants)):
        # If there is nothing, the pen is open:
        if not penOccupants[occIndex]:

            penOccupants[occIndex] = reindeer.id
            # Command the reindeer to move to the pen.
            hero.command(reindeer, "move", penPositions[occIndex])
            # break out early so we don't reassign:
            break
            pass

```

the moved in the code window but when i submited it gave me the same error and acted like it did not know what reindeer pos is

🫠 This took a while:  
On line 22 `friends[penIndex]` needs to be `friends[deerIndex]`. Otherwise It deletes the reindeer based on the pen positions array instead of the deer array.

That also explains why there was only one seed that worked for me 😅 because the penIndex and deerIndex lined up perfectly.

i changed ` if penPos == reindeer.pos:` to `if penPos.x == reindeer.pos.x and penPos.y == reindeer.pos.y: ` and it worked
