Write a python program called myTrip.py that uses functions to calculate your trip's costs. Note: You should display the costs to the user with proper prompts. Define a function called hotel_cost with one-argument nights as input. The hotel costs $140 per night. Therefore, the function hotel_cost should return 140 x nights. Define a function called plane_ride_cost that takes city names as input parameters. The function should return a different price depending on the location for a round trip. Below are the valid destinations and their corresponding one-way trip prices. "Charlotte": $183 "Tampa": $220 "Pittsburgh": $222 "Los Angeles": $475 Define a function called rental_car_cost with an argument called days. Calculate the cost of renting the car: Every day you rent the car costs $40 (cost = 40 x days). Return that cost. Then, define a function called trip_cost that takes city names and days as arguments, and have your function return the sum of calling the rental_car_cost (days), hotel_cost (days), and plane_ride_cost (city) functions – for each city. Modify your trip_cost function definition. Add a third argument, spending_money. Modify what the trip_cost function does. Add the variable spending_money to the sum that it returns. How hard is it to modify your program to update the per day and flight costs? Could you use constants at the top of your program to facilitate this?
