如何唯一化一个列表？

  • 772

有这样一个清单：

ls = [{'40', '39'},
      {'40', '39'},
      {'78', '82'},
      {'77', '81'},
      {'78', '82'},
      {'77', '81'},
      {'78', '82'}]

当然，我可以通过循环对其进行唯一化，但我想知道 Python 中是否有为此的标准功能？

    通过集：

    ls = [{'40', '39'},
      {'40', '39'},
      {'78', '82'},
      {'77', '81'},
      {'78', '82'},
      {'77', '81'},
      {'78', '82'}]
print(set(map(frozenset, ls)))
