python小白， 一组数据列表 每个元素由编号和坐标构成， 具体格式：（编号，x,y,z），编号定义的是线的顺序，假设列表里的编号是乱序的但是，想要一个函数能够将他们根据编号从大到小排列并且保证相同编号的元素顺序不能变。 排好序之后需要用光滑的圆弧连接相邻的前后两线，这个圆弧的编号用前者的就可以。圆弧根据连接不同有区分 如果直线都是横向或者纵向 用半圆弧连接 如果是横纵交错 用3/4圆连接。 麻烦各位大神了，具体可以加2410913785

补充：圆弧的坐标也需要输出 每15度插一个点就可以
两个问题， 一个排序， 一个画图。
> 想要一个函数能够将他们根据编号从大到小排列并且保证相同编号的元素顺序不能变。
这个不难完成吧， 如果编号相同， 为何有不同的元素呢？
