Battleship - Play it, Sam!


#1

Hey there :slight_smile:

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)

Thanks in advance!

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 :slight_smile:

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

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.
