python turtle四子棋

以下是一个简单的 Python Turtle 四子棋游戏代码示例：

import turtle

# 创建棋盘
def draw_board():
    turtle.speed(0)
    turtle.penup()
    turtle.setpos(-150, 150)
    turtle.pendown()
    turtle.pensize(3)
    for i in range(4):
        turtle.forward(300)
        turtle.right(90)
    turtle.penup()
    turtle.setpos(-150, 50)
    turtle.pendown()
    for i in range(3):
        turtle.forward(300)
        turtle.right(90)
    turtle.penup()
    turtle.setpos(-150, -50)
    turtle.pendown()
    for i in range(3):
        turtle.forward(300)
        turtle.right(90)

# 画棋子
def draw_piece(x, y, color):
    turtle.penup()
    turtle.setpos(x, y)
    turtle.pendown()
    turtle.dot(40, color)

# 判断胜负
def check_win(board, piece):
    for i in range(4):
        if board[i][0] == piece and board[i][1] == piece and board[i][2] == piece and board[i][3] == piece:
            return True
        if board[0][i] == piece and board[1][i] == piece and board[2][i] == piece and board[3][i] == piece:
            return True
    if board[0][0] == piece and board[1][1] == piece and board[2][2] == piece and board[3][3] == piece:
        return True
    if board[0][3] == piece and board[1][2] == piece and board[2][1] == piece and board[3][0] == piece:
        return True
    return False

# 主函数
def main():
    board = [[0 for i in range(4)] for j in range(4)] # 初始化棋盘
    player = 1 # 第一个玩家为红色
    draw_board() # 画棋盘
    while True:
        x, y = turtle.numinput("四子棋", "请输入下棋位置(x,y)：", default=(0, 0))
        x = int(x)
        y = int(y)
        if x < -150 or x > 150 or y < -150 or y > 150:
            continue
        i = (x + 150) // 100
        j = (y + 150) // 100
        if board[i][j] != 0:
            continue
        if player == 1:
            color = "red"
            piece = 1
            player = 2
        else:
            color = "blue"
            piece = 2
            player = 1
        draw_piece(i * 100 - 150, j * 100 - 150, color)
        board[i][j] = piece
        if check_win(board, piece):
            turtle.penup()
            turtle.setpos(-100, 0)
            turtle.pendown()
            turtle.write(color + " wins!", font=("Arial", 30, "normal"))
            break

    turtle.done()

if __name__ == "__main__":
    main()

该代码使用 Python Turtle 图形库绘制了一个简单的四子棋游戏界面，并实现了下棋、判断胜负等功能。在运行代码后，用户可以通过输入坐标来下棋，并根据游戏规则进行判断胜负。
