Hey, dudes, can you help me finding what is wrong in my code?
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 = cost -50 elif days >= 3: cost = cost - 20 return cost def trip_cost(days, city): return hotel_cost(days) + plane_ride_cost(city) + rental_car_cost(days)
Oops, try again. trip_cost('Charlotte', 4) raised an error: cannot concatenate 'str' and 'NoneType' objects
I just don't know what is wrong
I even tried to add a line like this
trip_cost(5, "Los Angeles")
not indented in the end of the code, but it does not work.
Help me pleeeeeassseee
