This is a simple battleship game, made with lists on python. This is the first game I ever made.

battleship.py

from random import randint

#initializing board
board = []

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

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

#starting the game and printing the board
print "Let's play Battleship!"
print_board(board)

#defining where the ship is
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)

#asking the user for a guess
for turn in range(4):
    guess_row = int(raw_input("Guess Row:"))
    guess_col = int(raw_input("Guess Col:"))

    # if the user's right, the game ends
    if guess_row == ship_row and guess_col == ship_col:
        print "Congratulations! You sunk my battleship!"
        break
    else:
        #warning if the guess is out of the board
        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."
        
        #warning if the guess was already made
        elif(board[guess_row][guess_col] == "X"):
            print "You guessed that one already."
        
        #if the guess is wrong, mark the point with an X and start again
        else:
            print "You missed my battleship!"
            board[guess_row][guess_col] = "X"
        
        # Print turn and board again here
        print "Turn " + str(turn+1) + " out of 4." 
        print_board(board)

#if the user have made 4 tries, it's game over
if turn >= 3:
    print "Game Over"

what does the print_board def do? i don't get theprint " "Join row

Also don't get the for loop

" ".join(row) joins together the elements in the list with a space between them.
And they're using a loop to have it print out with format of one row per print line instead of [[0,0,0,0,0],[0,0,0,0,0]........]

Dude, This is there in CODECADAMY, Don't try 2 fool us

Your last if statement is wrong, according to your comment, you state that if the user has had four attempts, it is game over. Currently, your if statement will print game over on the user third try and each try there after. If you want the user to get four attempts just put your if statement to if turn > 4.

This is from codecademy python course xD

The code doesn't work for me lmao..

Even though this is from Codecademy, I've made a new version for the people rocking V3.8.0 +.
Code:
`from random import randint

#initializing board
board = []

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

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

#starting the game and printing the board
print("Let's play Battleship!")
print_board(board)

#defining where the ship is
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)

#asking the user for a guess
for turn in range(4):
guess_row = int(input("Guess Row:"))
guess_col = int(input("Guess Col:"))

# if the user's right, the game ends
if guess_row == ship_row and guess_col == ship_col:
    print("Congratulations! You sunk my battleship!")
    break
else:
    #warning if the guess is out of the board
    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.")
    
    #warning if the guess was already made
    elif(board[guess_row][guess_col] == "X"):
        print("You guessed that one already.")
    
    #if the guess is wrong, mark the point with an X and start again
    else:
        print("You missed my battleship!")
        board[guess_row][guess_col] = "X"
    
    # Print turn and board again here
    print("Turn " + str(turn+1) + " out of 4.")
    print_board(board)

#if the user have made 4 tries, it's game over
if turn >= 3:
print("Game Over")
