示例代码（AI）：

import curses

def main(stdscr):
    # 禁用光标显示
    curses.curs_set(0)
    
    # 定义选项
    options = ["Option 1", "Option 2", "Option 3", "Exit"]
    current_row = 0
    
    # 定义一个函数来绘制当前的选项列表
    def print_menu(current_row):
        stdscr.clear()
        h, w = stdscr.getmaxyx()
        for idx, row in enumerate(options):
            x = w//2 - len(row)//2
            y = h//2 - len(options)//2 + idx
            if idx == current_row:
                stdscr.attron(curses.color_pair(1))
                stdscr.addstr(y, x, row)
                stdscr.attroff(curses.color_pair(1))
            else:
                stdscr.addstr(y, x, row)
        stdscr.refresh()
    
    # 设置颜色对
    curses.start_color()
    curses.init_pair(1, curses.COLOR_BLACK, curses.COLOR_WHITE)

    # 主循环
    while True:
        print_menu(current_row)
        key = stdscr.getch()
        
        if key == curses.KEY_UP and current_row > 0:
            current_row -= 1
        elif key == curses.KEY_DOWN and current_row < len(options) - 1:
            current_row += 1
        elif key == curses.KEY_ENTER or key in [10, 13]:
            if options[current_row] == "Exit":
                break
            stdscr.clear()
            stdscr.addstr(0, 0, f"You selected '{options[current_row]}'")
            stdscr.refresh()
            stdscr.getch()
    
    # 清除屏幕
    stdscr.clear()

# 运行 curses 应用
curses.wrapper(main)
