实际清单中的自定义清单（无重复） [英] Custom List from actual List (without duplicates)

问题描述

我有一个列表，如下所示：

I have a list , something like this:

list1<person>={elem1, elem2, elem3...}
and elem1 = name1, age1, haircolor1
    elem2 = name2, age2, haircolor2
    elem3 = name3, age3, haircolor3 ...

该列表包含重复项，意思是elem1标签可以与elem2标签相同，但内容（名称，年龄，发色）不同



我想要制作自定义列表：

The list contains duplicates, meaning elem1 label can be the same as elem2 label, but the contents (name, age, haircolor) are different

I want to make a custom list:

list2 = { elem1 = name1 age1 haircolor1
                  name3 age3 haircolor3

          elem2 = name2, age2, haircolor2
          elem4 = name4, age4, haircolor4
                  name6, age6, haircolor6
                  name7, age7, haircolor7 } 

谢谢！

Thank you!
