Моя программа не может генерировать количество пар, равное степени 2, если количество участников не является степенью 2. ⇐ Python

[Anonymous]

Я не могу решить эту чертову ошибку.
Программа не может делать следующее:
Если количество участников не является степенью 2, используются слова «пока» для автоматического перевода определенных участников в следующий раунд.
Например, у вас есть 4 парня в школе А и 2 парня в школе Б.
Его входные данные :
Enter school name (or 'done' to finish): A
Enter players for A (comma-separated): 1,2,3,4
Is 1 a semi-finalist from the last year? (y/n): n
Is 2 a semi-finalist from the last year? (y/n): n
Is 3 a semi-finalist from the last year? (y/n): n
Is 4 a semi-finalist from the last year? (y/n): n
Enter school name (or 'done' to finish): B
Enter players for B (comma-separated): 5,6
Is 5 a semi-finalist from the last year? (y/n): n
Is 6 a semi-finalist from the last year? (y/n): n
Enter school name (or 'done' to finish): done

Его вывод будет:
Pairings for Round 1:

1 (A) vs. 5 (B)
2 (A) vs. 6 (B)
3 (A) vs. 4 (A)

когда его вывод должен быть:
Pairings for Round 1:

1 (A) vs. 5 (B)
2 (A) vs. 6 (B)
Bye: 3 (A)
Bye: 4 (A)

По сути, если есть 3 игрока, в выходных данных должно быть 4 пары.
Если игроков 6, в выходных данных должно быть 8 пар.
Я порылся в программе, чтобы найти способ исправить ошибку, но не нашел ее.
