Problem Find all the combination of two in a team Solution 1 2 3 4 5 6 7 from itertools import combinations team = ["john", "joe", "bob", "al", "tony", "mark"] comb = combinations(team, 2) for i in list(comb): print(i) Result: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 ('john', 'joe') ('john', 'bob') ('john', 'al') ('john', 'tony') ('john', 'mark') ('joe', 'bob') ('joe', 'al') ('joe', 'tony') ('joe', 'mark') ('bob', 'al') ('bob', 'tony') ('bob', 'mark') ('al', 'tony') ('al', 'mark') ('tony', 'mark') Let’s up the game now we want to arrange the combinations results in a way that none of these guys are on call twice in a row...
