Python 缩进（制表符/间距错误）

Question

我通过 Python 制作了一个 'battleship' 程序，并决定构建我的代码（因为以前它很乱但工作正常）。但是，每当我运行我的代码时，它就会弹出一个缩进错误：

"File "python", line 29
guess_col = int(raw_input("Guess Col:"))
IndentationError: unindent does not match any outer indentation level"

我四处搜索，发现我使用了一些空格和制表符，所以我将它纯粹切换为制表符（缩进 4 个空格）。但是问题仍然存在，我不明白为什么。有谁能分享为什么会这样吗？

from random import randint
board = []
turn = 0
def print_board(board):
   for row in board:
       print " ".join(row)
def random_row(board):
    return randint(0, len(board) - 1)
def random_col(board):
    return randint(0, len(board) - 1)

#Start Battleship Functionality Here
print "Let's play Battleship!"
for x in range(5):
    board.append(["O"] * 5)
    print_board(board)

ship_row = random_row(board)
ship_col = random_col(board)
print ship_row
print ship_col


for turn in range(4):
    guess_row = int(raw_input("Guess Row:"))
    guess_col = int(raw_input("Guess Col:"))
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."
    print "Turn", turn + 1
elif (board[guess_row][guess_col] == "X"):
    print "You guessed that one already."
    print "Turn", turn + 1
elif guess_row == ship_row and guess_col == ship_col:
    print "Congratulations! You sunk my battleship!"
    print_board(board)
    break
elif turn == 3:
    print "Game Over"
else:
    print "You missed my battleship!"
    board[guess_row][guess_col] = "X"
    print "Turn", turn + 1
    print_board(board)

问题出在 For 语句中 - 因为我的 IF 在 for 循环下没有正确缩进，所以缩进级别不匹配。更正它导致程序运行顺利。

    for turn in range(4):
        guess_row = int(raw_input("Guess Row:"))
        guess_col = int(raw_input("Guess Col:"))

        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."
            print "Turn", turn + 1
            etc....
