Python3 permutations with tuples that contain duplicates

I want to create all the possible combinations of a tuple with duplicate elements.

For example lets say that we have {3,3,0}. I want the code to return: (3,3,0) (3,0,3) (0,3,3)

I looked at itertools documentation and at numerous stack overflow questions but i did not find a answer to this.

How can I implement it? Or, can this be implemented in general?

Solution

  • You could use permutations from itertools and then use a set to remove any doubles:

    result = set(permutations((3, 3, 0)))
