[PLUG] Seeking Algorithm

[Rich Shepard]

   I need an algorithm (or as expressed in python, perl, bash, whatever) to
generate all pairs of items from a list. In other words, if I have a list of
items, A ... B ... C ... D ... E, etc., I would like to automatically
generate the pairs AB, AC, AD, AE, BC, BD, BE, .... Permutations don't
matter, only the combinations.

   Can someone point me to a solution?

Thanks,

Rich
