title: Print statements are not printing to console, every time the function is called
body: <p>When I input the right integers to call either hit() or miss(), the print statements are printed to console the first time, but do not print to console, after that. 
  The players_turn() function gets called every time, but not the print statements.
  I do not get any errors in my console either</p>
  
  <pre><code>import numpy as np
  from random import randint
  
  board = []
  
  
  
  for x in range(0, 5):
      board.append(["O"] * 5)
  
  def print_board(board):
      for row in board:
          print (" ".join(row))
  
  def random_row(board):
    return randint(0, len(board) - 1)
  
  def random_col(board):
    return randint(0, len(board[0]) - 1)
  
  ship_row = random_row(board)
  ship_col = random_col(board)
  
  def players_turn():
      for turn in range(4):
      print ("turn", turn +1)
      guess_row = int(raw_input("Guess Row: "))
      guess_col = int(raw_input("Guess Col: "))
  
  def hit():
      print ("direct hit")
      board[guess_col][guess_row] = "H"
      print_board(board)
      players_turn()
  
  def miss():
      print ("you missed, try again")
      board[guess_col][guess_row]
      print_board(board)
      players_turn()
  
  def out_of_range():
      print ("this is out of the range of the battle field")
      players_turn()
  
  if_yes = str(raw_input("Do you want to play Battleship? "))
  
  if if_yes == 'yes':
      print ship_row
      print ship_col
      guess_row = int(raw_input("Guess Row: "))
      guess_col = int(raw_input("Guess Col: "))
  
  if guess_col == ship_col and guess_row == ship_row:
      hit()
  elif guess_col not in range(5) or guess_row not in range(5) :
      out_of_range()
  else:
      miss()
  </code></pre>
  
  <p>I am expecting that every time I input the correct hit() credentials, I will get: 
  "direct hit" and the board will be printed to console.
  If the miss() credentials are met I will get:
  "you missed, try again", and the board will be printed.</p>
