从任何顺序的python嵌套列表中删除重复的字符串

Question

[["hello", "bye", "start"], ["bye", "start", "hello"], ["john", "riya", "tom"], ["riya","john", "tom"].....]

我有一个这样的清单.我想从Python中的嵌套列表中删除重复元素,其中元素应该是任何顺序.

输出应为: -

[["hello", "bye", "start"], ["john", "riya", "tom"]]

3个字符串在任何列表中只应出现一次.怎么做到这一点？

简单地隐藏到set它会自动删除项目.

a = [list(i) for i in {frozenset(k) for k in a}]
