python 写一个程序 井字棋

以下是 Python 编写的井字棋程序：

def print_board(board):
    print("-------------")
    for i in range(3):
        print("|", end=" ")
        for j in range(3):
            print(board[i][j], "|", end=" ")
        print()
        print("-------------")

def check_win(board):
    for i in range(3):
        if board[i][0] == board[i][1] == board[i][2] and board[i][0] != " ":
            return True
        if board[0][i] == board[1][i] == board[2][i] and board[0][i] != " ":
            return True
    if board[0][0] == board[1][1] == board[2][2] and board[0][0] != " ":
        return True
    if board[0][2] == board[1][1] == board[2][0] and board[0][2] != " ":
        return True
    return False

def tic_tac_toe():
    board = [[" ", " ", " "], [" ", " ", " "], [" ", " ", " "]]
    player = "X"
    while True:
        print_board(board)
        row = int(input("Enter row number (1-3): ")) - 1
        col = int(input("Enter column number (1-3): ")) - 1
        if board[row][col] == " ":
            board[row][col] = player
            if check_win(board):
                print_board(board)
                print(player, "wins!")
                break
            if player == "X":
                player = "O"
            else:
                player = "X"
        else:
            print("That spot is already taken. Try again.")

tic_tac_toe()

这个程序实现了一个简单的井字棋游戏，玩家可以通过输入行和列的数字来下棋，程序会检查是否有玩家获胜。
