Operation on every pair of element in a list

result = [foo(people[p1], people[p2]) for p1 in range(len(people)) for p2 in range(p1+1,len(people))]
In case you don't want to operate but just to get the pairs, removing the function foo and using just a tuple would be enough.
All possible pairs, including duplicate...
