python五子棋

以下是一个简单的 Python 五子棋游戏的代码示例：

import os

# 创建一个15x15的棋盘，用"+"表示空位
board = []
for i in range(15):
    board.append(['+'] * 15)

# 打印当前棋盘状态
def print_board():
    os.system('cls')
    print(' ', end='')
    for i in range(15):
        print(chr(65+i), end=' ')
    print()
    for i in range(15):
        print(i+1, end=' ')
        for j in range(15):
            print(board[i][j], end=' ')
        print()

# 判断当前位置是否可下棋
def is_valid_move(row, col):
    return row >= 0 and row < 15 and col >= 0 and col < 15 and board[row][col] == '+'

# 判断是否已经有五子连线
def has_won(player):
    # 判断横向是否连线
    for i in range(15):
        for j in range(11):
            if board[i][j] == player and board[i][j+1] == player and board[i][j+2] == player and board[i][j+3] == player and board[i][j+4] == player:
                return True
    # 判断纵向是否连线
    for i in range(11):
        for j in range(15):
            if board[i][j] == player and board[i+1][j] == player and board[i+2][j] == player and board[i+3][j] == player and board[i+4][j] == player:
                return True
    # 判断左上到右下斜线是否连线
    for i in range(11):
        for j in range(11):
            if board[i][j] == player and board[i+1][j+1] == player and board[i+2][j+2] == player and board[i+3][j+3] == player and board[i+4][j+4] == player:
                return True
    # 判断右上到左下斜线是否连线
    for i in range(11):
        for j in range(4, 15):
            if board[i][j] == player and board[i+1][j-1] == player and board[i+2][j-2] == player and board[i+3][j-3] == player and board[i+4][j-4] == player:
                return True
    return False

# 开始游戏
def play_game():
    player = 'X'
    while True:
        print_board()
        row = int(input("Player %s, enter row: " % player))
        col = int(input("Player %s, enter column: " % player))
        if is_valid_move(row-1, col-1):
            board[row-1][col-1] = player
            if has_won(player):
                print_board()
                print("Player %s has won!" % player)
                break
            player = 'O' if player == 'X' else 'X'
        else:
            print("Invalid move, please try again.")

# 开始游戏
play_game()

该代码首先创建了一个 15x15 的棋盘，并用 `"+"` 表示空位。然后，定义了三个函数：`print_board` 用于打印当前棋盘状态，`is_valid_move` 用于判断当前位置是否可以下棋，`has_won` 用于判断是否已经有五子连线。最后，定义了一个 `play_game` 函数，用于开始游戏。该函数会不断循环，让两个玩家交替下棋，直到有玩家胜出。在每个玩家下棋之前，会先打印当前棋盘状态，并要求玩家输入要下棋的行和列。如果输入的位置合法，就会将对应位置的棋子状态改为当前玩家的标识符 (`"X"` 或 `"O"`)，然后判断是否有五子连线。如果有，则表示当前玩家胜出，游戏结束。否则，将轮到另一个玩家继续下棋。
