Python编写五子棋游戏

好的，下面是一个简单的五子棋游戏的 Python 代码：

import numpy as np

# 定义棋盘大小
BOARD_SIZE = 15

# 定义棋子类型
EMPTY = 0
BLACK = 1
WHITE = 2

# 定义棋盘
board = np.zeros((BOARD_SIZE, BOARD_SIZE), dtype=int)

# 判断是否胜利
def check_win(x, y, color):
    # 判断横向是否连续五个棋子
    count = 1
    for i in range(x-1, -1, -1):
        if board[i][y] == color:
            count += 1
        else:
            break
    for i in range(x+1, BOARD_SIZE):
        if board[i][y] == color:
            count += 1
        else:
            break
    if count >= 5:
        return True

    # 判断纵向是否连续五个棋子
    count = 1
    for j in range(y-1, -1, -1):
        if board[x][j] == color:
            count += 1
        else:
            break
    for j in range(y+1, BOARD_SIZE):
        if board[x][j] == color:
            count += 1
        else:
            break
    if count >= 5:
        return True

    # 判断左上到右下是否连续五个棋子
    count = 1
    for i, j in zip(range(x-1, -1, -1), range(y-1, -1, -1)):
        if board[i][j] == color:
            count += 1
        else:
            break
    for i, j in zip(range(x+1, BOARD_SIZE), range(y+1, BOARD_SIZE)):
        if board[i][j] == color:
            count += 1
        else:
            break
    if count >= 5:
        return True

    # 判断左下到右上是否连续五个棋子
    count = 1
    for i, j in zip(range(x+1, BOARD_SIZE), range(y-1, -1, -1)):
        if board[i][j] == color:
            count += 1
        else:
            break
    for i, j in zip(range(x-1, -1, -1), range(y+1, BOARD_SIZE)):
        if board[i][j] == color:
            count += 1
        else:
            break
    if count >= 5:
        return True

    return False

# 打印棋盘
def print_board():
    print("  ", end="")
    for i in range(BOARD_SIZE):
        print(chr(ord('A')+i), end=" ")
    print()
    for i in range(BOARD_SIZE):
        print("{:2d}".format(i+1), end="")
        for j in range(BOARD_SIZE):
            if board[i][j] == EMPTY:
                print("  ", end="")
            elif board[i][j] == BLACK:
                print("●", end="")
            else:
                print("○", end="")
            if j < BOARD_SIZE - 1:
                print(" ", end="")
        print()

# 主函数
def main():
    print("欢迎来到五子棋游戏！")
    print("游戏规则：先手执黑，后手执白，谁先连成五个棋子谁胜利。")
    print_board()
    color = BLACK
    while True:
        if color == BLACK:
            print("请黑方落子：")
        else:
            print("请白方落子：")
        move = input()
        x = ord(move[0].upper()) - ord('A')
        y = int(move[1:]) - 1
        if board[x][y] != EMPTY:
            print("该位置已经有棋子了，请重新落子！")
            continue
        board[x][y] = color
        if check_win(x, y, color):
            print_board()
            if color == BLACK:
                print("黑方胜利！")
            else:
                print("白方胜利！")
            break
        print_board()
        color = WHITE if color == BLACK else BLACK

if __name__ == "__main__":
    main()

这个程序使用 `numpy` 模块定义了一个 `BOARD_SIZE × BOARD_SIZE` 的二维数组 `board` 来表示棋盘状态，通过 `check_win` 函数判断是否胜利，通过 `print_board` 函数打印棋盘状态。主函数通过不断的输入落子位置，更新棋盘状态并判断胜利条件，最终输出胜利方。

通过这个简单的五子棋游戏，你可以熟悉 Python 中的二维数组和字符串处理，加深对条件判断和循环语句的理解。
