  • Защо правиш това object.__setattr__(self, 'rank', rank())? В python си има синтаксис за тази операция
  • Не правиш for-ове и if-ове на един ред
  • Виж list.pop, това ще ти помогне да имплементираш CardCollection.draw като хората
  • Тестетата си имат строго определен ред

  1. Използвам object.setattr() заради поведението на Rank.setattr(). Не намерих по-чисто решение, но може да пропускам нещо очевидно!?

  2. Ако събера целия блок на 71-ви ред стават над 70 символа.

  3. Без коментар за последните две точки
