Hi Mathew Yangang (https://teamtreehouse.com/mathewyangang),
You can only process a single return from a function but I can see what you were trying to achieve there.  Since that isn't an option however we can use the random.sample function from Python random, which returns a list.  
From the python documentation found here: Python 3 - Random (https://docs.python.org/3/library/random.html)  
random.sample(population, k)  
Return a k length list of unique elements chosen from the population sequence or set. Used for random sampling without replacement.  
So with that in mind, you could try something like:  
Python  
return random.sample(cells, 3)
  
Keep on coding!  
Dave :dizzy:  
P.S. You can just delete that pass from the challenge ... not sure why they put that there.
