Answer for 3/7


#1
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

#2

Throw a else: return in there at the bottom. :smile:


#3

your "return "after the hotel_cost has the wrong indentation
it should have four spaces and to make it easier you can just press TAB at the beginning of a line or where ever, then it will add four spaces.
