import randomdef random_door(): return random.randint(1, 3) 请根据下面错误提示：NameError: name 'random' is not defined。修改这段代码

这个错误提示表示代码中使用了 `random`，但是 Python 并不知道 `random` 是什么。这种情况通常是因为没有正确导入相关的模块。

因此，我们需要在代码开头导入 `random` 模块。修改后的代码如下：

import random

def random_door():
    return random.randint(1, 3)

这样就可以解决 `NameError: name 'random' is not defined` 的问题了。

这段代码是一个猜数字的小游戏，使用tkinter库创建了一个GUI界面，玩家需要输入1到100之间的数字来猜测随机生成的目标数字，每次猜测后会给出相应的提示并显示剩余的猜测次数，若玩家在给定次数内猜对了，会弹出恭喜的提示，否则会弹出失败的提示。
