Няколко неща за коментарите:

  • "Header" документацията в Python е прието да се прави с triple quotes - '''This is some multiline documentation'''. Не сме говорили за това, но ще се възползваме от възможността по време на следващата лекция.
  • Коментари като #default би следвало да се подразбират от кода ти. Ако е за лично удобство в началото - няма грижи, но по принцип коментари от типа на speed = 50 # Set speed to 50 са излишни in general. Твоят не е толкова "безочлив", но го казвам за да го имаш предвид. :D
  • Това са домашни и е окей да има "debug" print-ове наляво надясно, гледай да третираш проекта след няколко месеца като production код и да не оставяш много такива.
