A simple python script that creates randomised pairings of elements from an input list. So for example the input list:
A B C D
Might be paired as:
A -> D
B -> C
C -> A
D -> B
Elements are guaranteed not to be paired with either themselves of with a reciprocal relationship ( A -> B and B -> A).
The intention of this script was originally to put people randomly in contact with one another, so given a list of names, the script can create a list of informal random introductions between people.
