既然你想找到无序的重复，***的方法是通过类型转换.Typecast 它们为 set.因为 set 只包含 immutable 元素.所以，我做了一组tuples.

Since you want to find unordered duplicates the best way to go is by typecasting. Typecast them as set. Since set only contains immutable elements. So, I made a set of tuples.

注意:消除重复的***方法是对给定元素进行set.

Note: The best way to eliminate duplicates is by making a set of the given elements.

>>> set(map(tuple,map(sorted,x)))
{(-3, -2, 4, 5), (-5, 0, 4, 5)}
