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): return (cost-50) elif (days>=3): return cost-20 else: return cost def trip_cost(city,days): rental_car_cost(days) hotel_cost(days) plane_ride_cost(city) print trip_cost("Tampa",7)
your trip_cost function should add the rental car, hotel and plane ride cost together and return this total trip cost
When I seperately call single fuction it says it returns none
calling the function causes numbers (integers) to be returned, which you should add together. This result should be returned
Thank you for the help!
