18/19 - 4 guesses but game over at 3?


#1

`
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!"
    break
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 + 1) here!
    # print_board(board)
    turn = turn + 1
    print turn    
    
    if turn == 3:
        print "Game Over"
        break

I am not quite sure what the lesson's intent was. Please can someone help explain?
Earlier we made a for loop for 4 guesses, but at lesson 16, we wanted to 'game over' after the 3rd, so here I added when turn equals 3, it prints game over. however, after that, user can still make the 4th guess. What was the instructor's intent here? I added a break after printing 'game over', not sure if this is right, or should I change the range(4) to range (3) in the 'turn' for loop.?

from random import randint

board = []
turn = 0

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 "Turn"
print turn + 1

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!

turn = 0
for turn in range(4):
print (turn + 1)

if turn == 3:
print "Game Over"

guess_row = int(raw_input("Guess Row:"))
guess_col = int(raw_input("Guess Col:"))

while guess_row == ship_row and guess_col == ship_col:
print "Congratulations! You sunk my battleship!"
break
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"
turn = turn + 1
print "Turn", turn
print_board(board)
