# Play It, Sam

I wonder why the loop does not stop while i type the correct answer and it keeps showing "Oops, try again. Did you remember to print out turn + 1 each turn? ". Thank you so mcuh

``````from random import randint

board = []

for x in range(5):
board.append(["O"] * 5)

def print_board(board):
for row in board:
print " ".join(row)

print "Let's play Battleship!"
print_board(board)

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)
print ship_row
print ship_col
# Everything from here on should go in your for loop!
# Be sure to indent four spaces!
for turn in range(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."
break
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 (turn + 1) here!
print "Turn+", str(turn+1)
print_board(board)``````

I had that problem too. Apparently, it should look like this:

``````for turn in range(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 "Turn", turn + 1
print_board(board)``````

Notice how the print lines at the bottom are at the same indentation level as your first if statement.

I don't think it must be in the same indentation level with the "else" statement. The problem with the code is converting the result into a string when it should actually be an integer as defined in the range call above, only with this can the addition can take place.

I'm pretty sure this code never converts anything to a string. Therefore, I can safely say that it is just the indentation thing.

Sorry, I was referring to cloudjumper's code, not yours.
