In mathematics, the notion of permutation relates to the act of arranging all the members of a set into some sequence or order, or if the set is already ordered, rearranging (reordering) its elements, a process called permuting. Python provides direct methods to find permutations and combinations of a sequence. So, if I start with two lists like this: That is, it basically produces a list of lists, with all the potential combinations between the two. With list comprehension, you can easily loop through all combinations of 2 or 3 lists. This recipe show a way to do this, without use of recursion.
