Code not running properly in IDLE


Traceback (most recent call last):
File "", line 28, in
guess_row = int(raw_input("Guess Row:"))
NameError: name 'raw_input' is not defined

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!")

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)

for turn in range(4):
    print("Turn", 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!")
    elif (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.")
        print("You missed my battleship!")
        board[guess_row][guess_col] = "X"
    if turn == 3:
        print("Game Over")

My code works just fine in codecademy, but when I tried it in IDLE it gave me that error. Any reason why? (The version is 3.6.1 if that helps)


raw_input() no longer exist in python3, its renamed to input()


I've also noticed that you need to use parentheses if you're using print, does any other thing change that I need to know of?


well, you might encounter a few different changes like:

Python has also docs about the changes, you can google to find this. But you have most now
