i have list of names that i want to match for a tennis competition. The games are taking place once a week and everyone should have a new opponent each week till all pairings have been made. To create 2 people combinations with all the players I did the following: from itertools import combinations names = [‘ben’, ‘josh’, ‘jessy’, ‘natalia’] result = [[a + ‘-‘ + b] for a, b in combinations(names, 2)] This gives the following: [['ben - josh'], ['ben - jessy'], [‘ben - natalia'], ['josh - jessy'], ['josh - natalia'], ['jessy - natalia']] The last part is to match each player with someone who they’ve never played before. In order to do this i did the following: for i, j in zip(range(int(len(result)/2)), (reversed(range(int(len(result) /2),len(result))))): print(result, result[j] This way each player plays with someone new each time. The result is: ['ben - josh'] ['jessy - natalia'] ['ben - jessy'] ['josh - natalia'] ['ben - natalia'] ['josh - jessy'] How I can extend the following to a much bigger list of players ? Lets say 100+ ? Is there any better way of doing this ? Also, what if the list of players has odd number of players ? Thanks for your help with this. Continue reading...
