   Purpose:  Implement some functions that can be used in a program
             that plays blackjack

   Run:      python play_cards1.py

   Input:    Number of hands
   Output:   Each player's hand.  (This shows the dealer's hole card.)
   Note:     Cards are represented as tuples consisting of two strings
             strings:  Ranks are 'A', '2', . . . , '10', 'J', 'Q', 'K'
             Suits are 'C', 'D', 'H', 'S'
