Hi all,
I am wondering if there is a python package that will find
permutations? For example, if I have (1, 2, 3), the possibilities I
want are:
12
13
23
123
132
231
Order does not matter; 21 is the same as 12, but no numbers can
repeat. If no package exists, does someone have a hint as to how to
get a function to do this? The one I have right now will not find 132
or 231, nor will it find 13. TIA.
According to Wikipedia " there are six permutations of the set {1,2,3},
namely [1,2,3], [1,3,2], [2,1,3], [2,3,1], [3,1,2], and [3,2,1]."
Above you show some "combinations" and a subset of the permutations.
What rules did you apply to come up with your result?
