删除与生成器Python 3.5中具有相同元素的顺序无关的重复元组

问题描述

我有一个元组生成器，我需要删除包含相同元素的元组.我需要此输出进行迭代.

I have a generator of tuples and I need to delete tuples containing same elements. I need this output for iterating.

Input = ((1, 1), (1, 2), (1, 3), (3, 1), (3, 2), (3, 3))

Output= ((1, 1), (1, 2), (1, 3))

输出顺序无关紧要.

我已经检查了此问题，但它与列表有关:

I have checked this question but it is about lists: Delete duplicate tuples with same elements in nested list Python

由于数据非常大，我使用生成器来获得最快的结果.

I use generators to achieve fastest results as the data is very large.

推荐答案

您可以通过对数据进行排序来规范化数据，然后将其添加到数据集中以删除重复项

You can normalize the data by sorting it, then add it to a set to remove duplicates

>>> Input = ((1, 1), (1, 2), (1, 3), (3, 1), (3, 2), (3, 3))
>>> Output = set(tuple(sorted(t)) for t in Input)
>>> Output
{(1, 2), (1, 3), (2, 3), (1, 1), (3, 3)}
