Oops, try again. Did you remember to print out turn + 1 each turn?

I had expected the code to run as task says let the player know what turn they are on

``````turn =0
for turn in range (0,4):
guess_row = int(raw_input("Guess Row:"))
guess_col = int(raw_input("Guess Col:"))

if guess_row == ship_row and guess_col == ship_col:
print "Congratulations! You sunk my battleship!"
else:
if (guess_row < 0 or guess_row > 4) or (guess_col < 0 or guess_col > 4):
print "Oops, that's not even in the ocean."
elif(board[guess_row][guess_col] == "X"):
print "You guessed that one already."
else:
print "You missed my battleship!"
board[guess_row][guess_col] = "X"
print_board(board)
print ("Turn", turn + 1)``````

What happens if you write it like,

``print turn + 1``

?
