This is an object oriented programming problem. You will need to create three python files: main.py and airplane.py. You cannot import any sorting methods in this question. The file airplane.py contains an object called class Airplane that stores the ID number of a single airplane (named planelD) and the number of passengers (named numPassengers), the priority of the flight (named flightPriority) and the time of the flight (named flightTime) of that single airplane. The object has a constructor that assigns string planelD, integer numPassengers, integer flightPriority and integer flightTime with the values passed to it. For simplicity assue time is an integer number of this form: 2:30PM is recorded as integer 1430 using 24-hour time. Assume priority is an integer number between 0 and 10 with O being the highest priority and 10 the lowest priority. Write the methods named getPriority(), getTime() and getPlanelD() which return the corresponding class variable. The file main.py contains the main program. Do the following: 1. Create a list called planesList that stores Airplane objects. Initialize the list to empty. This variable represents a lineup of airplanes at a particular runway as they wait their turn to fly. 2. Write a function called addPlane(ID.passengerCount,priority,time) that instantiates and adds an Airplane object to planesList sorted by lineup position number. The list's index number is the airplane's lineup position on the runway as it waits its turn to fly. Index 0 is first in line, with index 1 being after that, etc. Each airplane must have a unique lineup position number. The position of the airplane is determined by this formula: earlier timed airplanes go before later timed airplanes, unless the times are the same, then the priority determines which goes first, unless the priority is the same, then it is ordered by last one first. 3. Call the function addPlan() four times adding 4 different airplanes to the list. 4. Print planesList to the screen in their flight position orde. Your program does not ask for input from the user. Everything is hard coded.
