Указывайте строку где ошибка и кидайте сам код ошибки

Dmitrii, 84, 98 строка

Magixy, оборачивайте traceback тэгом code для корректного отображения.

И обратите внимание на п.3.6 Правил.

[Максим Припадчев]

У вас DaysCar пустая строка, TotalCost, Prc пустые строки, так что код абсолютно не рабочий.
