title: dictionary function .popitem() is not returning random key-value pair
body: <p>I have code where the .popitem() function is not returning random key-value pairs. Instead it is popping them sequentially from the last one back.
  The function should be randomly dealing the &quot;cards&quot;. Is there something I'm missing?</p>
  <pre><code># This program uses a dictionary as a deck of cards
  
  def main():
      # Create a deck of cards.
      deck = create_deck()
  
      # Get the number of cards to deal
      num_cards = int(input('How many cards should I deal? '))
  
      # Deal the cards
      deal_cards(deck, num_cards)
  
  # The create_deck function returns a dictionary representing a deck of cards
  def create_deck():
      
      deck = {'Ace of Spades':1, '2 of Spades':2, '3 of Spades':3, '4 of Spades':4, '5 of Spades':5,
              '6 of Spades':6, '7 of Spades':7, '8 of Spades':8, '9 of Spades':9, '10 of Spades':10,
              'Jack of Spades':10, 'Queen of Spades':10, 'King of Spades':10,
              'Ace of Hearts':1, '2 of Hearts':2, '3 of Hearts':3, '4 of Hearts':4, '5 of Hearts':5,

  # The deal_cards function deals a specified number of cards from the deck
  
  def deal_cards(deck, number):
      # Initialize an accumulator for the hand value
      hand_value = 0
  
      # Make sure the number of cards to deal is not greater than the number of cards in the box
      if number &gt; len(deck):
          number = len(deck)
  
      # Deal the cards and accumulate their values.
      for count in range(number):
          card, value = deck.popitem()
          print(card)
