Можеш да минеш и само с един
passв тялото на класа, защото този инициализатор реално не прави нищо.Главните букви оказват константи, т.е. не е прието да имаш аргументи, които да са с главни букви, било то и абревиатури.
Това можеш да го генерираш с малко лист компрехеншън и умможение на листове.
За тези валидации те съветвам да огледаш другите решения. Има къси методи за справяне с проблема.
Избягвай пренасяне на редове с наклонена черта на всяка цена. Можеш да използваш цикли, променливи, функции, но не и това.
