Accessing attributes of Python object in an object in a list

I am very new to Python and OOP so if there is any additional info I missed or errors in my code/logic I am hopeful for helpful criticism.

I have an object in the location class initialized as such:

class Location:
   def __init__(self,x,y):
        self.x = x
        self.y = y

location1 = Location(0,0)
location2 = Location(1,1)

This object is then passed as an attribute into a class called Passenger and a class called Car, which are both initialized as such:

class Passenger:
    def __init__(self, passenger_name, location):
        self.passenger_name = passenger_name
        self.location = location

passenger1 = Passenger("John Doe", location1)

class Car:
    def __init__(self, car_name, location, cost_per_mile):
        self.car_name = car_name
        self.location = location
        self.cost_per_mile = cost_per_mile

car1 = Car("car1", location2, 0.5)

Then finally, I have a class initialized into the variable "mobileApp"

class CarSharingApp:
    cars = []
    passengers = []

    def __init__(self):
        pass

    def add_car(self,car):
        CarSharingApp.cars.append(car)
        print(f"Car successfully added.")

    def add_passenger(self, passenger):
        CarSharingApp.passengers.append(passenger)
        print(f"Passenger successfully added.")

mobileApp = CarSharingApp()
mobileApp.add_car(car1)
mobileApp.add_passenger(passenger1)

that holds a list of these passenger and car objects (which still both hold the Location objects inside them) as CLASS attributes rather than an instance attribute in a list naturally named "passengers" and "cars". My QUESTION is how can I now access the (x,y) coordinates of these car and passenger objects in order to use them in an equation? I need to essentially find the distance between cars and passengers.I know how to access the list itself, but not the location objects x and y attributes nested in the list of objects.

Solution

Note that you are modifying the CarSharingApp.cars and not self.cars, so the cars will be appended to CarSharingApp.cars instead of mobileApp.cars

CarSharingApp.cars is a list containing car objects. CarSharingApp.cars[0] accesses the first car, CarSharingApp.cars[0].location accesses the location object of the first car And CarSharingApp.cars[0].location.x accesses its x coordinate

x_coordinate_of_first_car  = CarSharingApp.cars[0].location.x
y_coordinate_of_first_car = CarSharingApp.cars[0].location.y
# similarly
x_coordinate_of_first_passenger = CarSharingApp.passengers[0].location.x
y_coordinate_of_first_passenger = CarSharingApp.passengers[0].location.y
