title: Random.sample outputs a 3 dimensional array
body: <p>I am using a two dimensional array(a deck) and I am trying to random.sample to fill another list with 5 random items. Though, i get a 3 dimensional list and I cannot fix it</p>
  
  <p>Any help?</p>
  
  <pre><code>import random
  suits =['H', 'D', 'S', 'C']
  numbers = []
  deck = []
  for i in range(0, 13):
   numbers.append(i+2)
  for i in range(len(suits)):
   for j in range(len(numbers)):
      deck.append([numbers[j], suits[i]])
  player1 = []
  pc = []
  for i in range(5):
   player1.append(random.sample(deck, 1))
   pc.append(random.sample(deck, 1))
   print(player1,pc)
  </code></pre>
  
  <p>Output:[[[14, 'C']], [[11, 'D']], [[6, 'C']], [[14, 'S']], [[13, 'H']]] [[[2, 'C']], [[6, 'D']], [[11, 'C']], [[6, 'D']], [[9, 'S']]]... I Just cannot get rid of the extra list that's created(I need to use .sample and not .choice which worked fine before)</p>
  
  <p>Thanks in advance,</p>
