On exercise 4/7 : transportation , i wrote this :
def rental_car_cost(days): money = days*40 if days >= 7: money -= 50 elif days >=3: money -=20 print money rental_car_cost(1)
Yet the answer is : 40
And i got this message :
Oops, try again. It looks like rental_car_cost returns None instead of the correct amount (40) for 1 days.
HELP ME PLEASE !!!!
