預計Python遊戲中的縮進塊

Question

我正在編寫一個程序來玩連接四個Python，我不確定如何解決在某些區域拋出的「預期縮進塊」錯誤。任何時候我嘗試運行[row] [col]部分，都會引發錯誤。我使用的一些示例代碼，以幫助我發展我自己和這裏的我使用的是什麼：

import random 

def winner(board): 
"""This function accepts the Connect 4 board as a parameter. 
If there is no winner, the function will return the empty string "". 
If the user has won, it will return 'X', and if the computer has 
won it will return 'O'.""" 

# Check rows for winner 
for row in range(6): 
for col in range(3): 
    if (board[row][col] == board[row][col + 1] == board[row][col + 2] ==\ 
     board[row][col + 3]) and (board[row][col] != " "): 
    return board[row][col] 

# Check columns for winner 
for col in range(6): 
for row in range(3): 
    if (board[row][col] == board[row + 1][col] == board[row + 2][col] ==\ 
     board[row + 3][col]) and (board[row][col] != " "): 
     return board[row][col] 

# Check diagonal (top-left to bottom-right) for winner 

for row in range(3): 
for col in range(4): 
    if (board[row][col] == board[row + 1][col + 1] == board[row + 2][col + 2] ==\ 
     board[row + 3][col + 3]) and (board[row][col] != " "): 
     return board[row][col] 


# Check diagonal (bottom-left to top-right) for winner 

for row in range(5, 2, -1): 
for col in range(3): 
    if (board[row][col] == board[row - 1][col + 1] == board[row - 2][col + 2] ==\ 
     board[row - 3][col + 3]) and (board[row][col] != " "): 
     return board[row][col] 

# No winner: return the empty string 
return ""

Answer 1

它看起來像你沒有縮進你的for循環：

for row in range(6): for col in range(3): if (board[row][col] == board[row][col + 1] == board[row][col + 2] ==\ board[row][col + 3]) and (board[row][col] != " "): return board[row][col]

的:表示對下一行縮進的需要。

Answer 2

由於無法解釋的原因，有很多地方的縮進只是普通的缺失。正如@davidism所提到的，python中的縮進用於表示嵌套層次;所以這個代碼在當前狀態下是完全不可用的。

這裏是我嘗試讓GUESS知道你的代碼是做什麼的，所以你可以瞭解空白的所有地方，但它只是在你的代碼中缺少。

import random 


def winner(board): 
    for row in range(6): 
     for col in range(3): 
      if (board[row][col] == board[row][col + 1] == board[row][col + 2] == \ 
         board[row][col + 3]) and (board[row][col] != " "): 
       return board[row][col] # Check columns for winner 

    for col in range(6): 
     for row in range(3): 
      if (board[row][col] == board[row + 1][col] == board[row + 2][col] == \ 
        board[row + 3][col]) and (board[row][col] != " "): 
       return board[row][col] 

# Check diagonal (top-left to bottom-right) for winner 

    for row in range(3): 
     for col in range(4): 
      if (board[row][col] == board[row + 1][col + 1] == board[row + 2][col + 2] == \ 
        board[row + 3][col + 3]) and (board[row][col] != " "): 
       return board[row][col] 


# Check diagonal (bottom-left to top-right) for winner 

    for row in range(5, 2, -1): 
     for col in range(3): 
      if (board[row][col] == board[row - 1][col + 1] == board[row - 2][col + 2] == \
