Battleship - Play it, Sam!

#1

Hey there

I get the following error:

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

However, in my test runs, my program prints the correct turns. I tried it at different place within the for loop and always get the same error. Can anyone help?

``````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

for turn in range(4):
print "Turn" + str(turn+1)
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)``````

Don't worry, it's just a common typo in your line:

``print "Turn" + str(turn+1)``

The CodeAcademy courses are very specific about what text you print, so it needs to be exact. Add a space after "Turn", so it looks like this:

``print "Turn " + str(turn+1)``

If this solves your question, please be so kind as to mark this as the solution

just print (turn+1) instead of print "Turn" + str(turn+1)
i think it works

#4

I have the same problem:

``````for turn in range(4):
print "Turn " + str(turn+1)
print "Guess 1 through 5"
guess_row = int(raw_input("Guess Row:")) - 1
guess_col = int(raw_input("Guess Col:")) - 1

if guess_row == ship_row and guess_col == ship_col:
print "Congratulations! You sank my battleship!"
else:
if guess_row not in range(5) or guess_col not in range(5):
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)``````

It runs fine, prints out the turn but I still get: "Oops, try again. Did you remember to print out turn +1 each turn?"

Ok i did run the

``````for turn in range(4):
print (turn+1)``````

Which only prints out just the #.

Where this actually prints out the Turn and #.

``print "Turn " + str(turn+1)``

I think the directions need to have the wording corrected.
