по-добрата практика е съобщението при изключение е да се подава като аргумент:

raise NotYourTurn("It's not your turn!")

Ако наследяваш Exception не е нужно да добавяш message атрибут. Неговия конструктор има атрибут args и str(exception) връща първият аргумент подаден на конструктора.

Накратко -- по-добре направи изключенията си така:

class NotYourTurn(Exception):
    pass

и ги извиквай както ти показах.

Изпускаш случаи, в които играч е победител.

Също изпускаш един от случаите, когато би трябвало да възбудиш изключение.

Помисли дали не можеш да направиш метода __str__ чрез форматиране на низ(ове).

1) "\n{border}{}{border}{}{border}{}{border} A B C \n".format(*line[::-1], border=dashes)

2) В wins имаш не малко повторения, които лесно можеш да избегнеш като направиш някаква абстракция по тройка_победни_полета.
