Python缩进（制表符/间距错误）

我已经通过Python制作了一个'battleship'程序，并决定构建我的代码（因为之前它很杂乱，但工作正常）。然而，每当我跑我的代码现在会弹出一个压痕错误：Python缩进（制表符/间距错误）

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

我搜索周围，意识到我已经使用了一些空间以及标签，所以我切换它纯粹是标签（缩进的4个空格）。然而问题仍然存在，我不明白为什么。有人能够分享为什么这可能是？

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)

另外：Python的通用标准是专门使用空格。请参阅https://www.python.org/dev/peps/pep-0008/#tabs-or-spaces另外，上面粘贴的代码似乎是空格和制表符的混合。 –

哦，感谢那个Rob！你有什么想法为什么会出现这个错误？ – azurekirby

可能因为您仍然有一些制表符和空格。 –

问题出在For语句 - 因为我的IF没有正确缩进for循环下面，缩进级别不匹配。修正它导致程序顺利运行。

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....

感谢大家的意见！
