7 Info2000 Airlines Write a program that asks users for their destination from Athens and gives them the cost of a flight to get there (similar to the example we did in class on 2/7/2023). Complete the class exercise such that, if the user enters a destination that's not in the dictionary, the user has the option of adding the destination and its 4 mileage to the dictionary. Then, the destination should be accessible in future loops. The work from class can be found here: https://github.com/rukangu/infoClassWork.git i.e if a user enters 'Nairobi' and it's not in the dictionary, the program should ask them if they would like to add Nairobi to the dictionary of destinations. If they reply with anything else apart from ' y ' or ' Y ', proceed with asking them for another destination. Otherwise, if the user replies with ' Y ' or ' y ', prompt them for the mileage to Nairobi and add Nairobi and the mileage as a key - value pair to the dictionary. Test your code with multiple destinations and confirm that any new destinations that you add are accessible in future iterations of the loop. Where would you like to travel to?
