Lesson 8. Taking a vacation, Hey, you never know



Apparently trip_cost only takes 3 arguments when the exact instructions say to add another argument

Oops, try again. trip_cost should take exactly 3 arguments!

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
    elif city == "Los Angeles":
        return 475
        "Stay home"

def rental_car_cost(days):
    cost = days * 40
    if days >= 7:
        return cost - 50
    elif days >= 3:
        return cost - 20
    return cost

def spending_money(misc):
    50 * misc
    return misc

def trip_cost(city, days):
    return sum([rental_car_cost(days), hotel_cost(days), plane_ride_cost(city)])
    total = sum
    return Sum + spending_money


def trip_cost(city, days, spending_money):
    cost_list = [rental_car_cost(days), hotel_cost(days), plane_ride_cost(city), spending_money]
    total_cost = sum(cost_list)
    return total_cost

trip_cost() takes three arguments: city, days, spending_money.

The list should have: rental_car_cost(days), hotel_cost(days), plane_ride_cost(city), spending_money

sum() is one of Python's built-in functions. Remove the first "return" keyword. Assign the sum to "total" variable. Add spending_money to the list. Finally, return the total.


I understand that but why was i not told in the instructions to make a list especially since list weren't even covered yet?


I'm very new to this but I think this is how you're intended to do it.

def trip_cost(city,days,spending_cost):
return rental_car_cost(days) + hotel_cost(days) + plane_ride_cost(city) + spending_cost
