Python实现一笔画游戏

关于一笔画介绍可参见“HTML5实现一笔画游戏”https://blog.csdn.net/cnds123/article/details/136669088

在Python中，Tkinter是一个广泛使用的标准GUI库，我们将使用它来实现这个游戏。

先给出效果图：

连接线段时，必须按照一定的顺序来连接点。
两点间连线方法：从一个点按下鼠标左键拖动到释放。

源码如下：

说明，定义不同难度的关卡数据：

const levels = {
    "easy ":{
          // 定义简单难度的点和线段
    },
    "medium": {
        // 定义中等难度的点和线段
    },
    "hard": {
        // 定义高难度的点和线段
    }
};

这些点的 x 和 y 坐标是基于画布的尺寸和布局预设的。你可能需要根据你的具体实现调整这些坐标值，以确保点和线在你的游戏界面中正确显示。此外，这些关卡设计仅作为示例，你可以根据需要调整点和线的数量及布局，创造出更多不同难度的关卡。
