But that doesn't really help you. When you do seq[::step], step is evaluated once and used for the whole extended slice. So in almost all cases that you are likely to encounter, step is 2, so you'll get seq[0], seq[2], seq[4], etc. Even if step is some other positive number, seq[0] will always be chosen. > The "byes = #whatever" in my code calculate the number of > tuples that need to be placed in the bye_list. Fine, but that's not the number of byes that you put into bye_list. > At first glance, the suggestion of adding a simple shift > at the end of round_robin doesn't seem to work since > round_robin already shifts everything except for the first > position already. Please correct me if I'm wrong because > you might have been suggesting something different. If you read my post carefully, you would see that you HAVE to do something about the first player always being stuck in the first spot. Either move him around, or select your byes differently. That said, I've played around with the shuffling a bit, and it does seem to be pretty tricky to get it to work for the general case where there is no prior knowledge of how many players and courts you will have. I can't shake the feeling that someone good at math will be able to figure out something elegant; but if left to my own devices, I am starting to lean toward just generating all the possible matches and somehow picking from them as needed to fill the courts, trying to keep the number of matches played by each player as close to equal as possible, and trying to keep the waiting times approximately equal as well.
