Hi there.

Writing hash by itself doesn't create a new Hash in Ruby. There're couple ways to do it here.

def create_shopping_list
  return {}
end

def create_shopping_list
  return Hash.new   # create new instance of Hash
end

Hope it helps.

You have to initiate new hash by like this def create_shopping_list return Hash.new end this method will create new empty hash for you can add keys and values in it later on.
