7/7 Plan your trip



no errors i just dont understand how it picks up 5 as days and 600 as spending money

how does it know 5 goes to days and 600 goes to spending money?

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

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)


Hi It know it because of the function you made trip_cost which takes as parameter city, days, spending_money

def trip_cost(city, days, spending_money):

if you look to your call function you'll see that (the argument are in the same order of the paramters)

trip_cost(city, days, spending_money): #this is the function
trip_cost("Los Angeles", 5, 600) #this is the call function

first you put city("Los Angeles") then days(5) and spending_money(600)
