I have a problem to print the result.
I use print function befior and after line with return rental_car_cost(days) + hotel_cost(days) + plane_ride_cost(city) + spending_money. If it' s before i have None in Console, if it's after return i have alert: "Oops, try again. It looks like nothing was printed to the console!"
Please HELP! I'd like to see the result of print function in console window.
