7 Plan Your Trip!
Hello everyone! I'm a total beginner with programming and coding, I think I need some extra help to understand some of these exercises.
I managed to complete the task 7. Plan Your Trip!, the fact is I think I missed why it actually works. To be precise, why replacing hotel_cost(nights) with hotel_cost(days) still makes the whole function work? I can't see how hotel_cost(nights) and rental_car_cost(days) are related, can someone explain it to me?
(I tried to add a fourth argument to the final function making no changes to the hotel_cost(nights) function, the result is the same, but the exercise requires me to solve it exactly with three arguments)
Thanks for the help.
def hotel_cost(nights): return 140 * nights def plane_ride_cost(city): if city == "Charlotte": return 183 elif city == "Tampa": return 220 elif city == "Pittsburgh": return 222 else: return 475 def rental_car_cost(days): total = 40 * days if days >= 7: total -= 50 elif days >=3: total -= 20 return total def trip_cost(city, days, spending_money): return hotel_cost(days) + plane_ride_cost(city) + rental_car_cost(days) + spending_money print trip_cost("Los Angeles", 5, 600)
