Question

Hey everyone, my problem is that im trying to figure out how to get a class INSIDE another class.

What I am doing is I have a class for an Airplane with all its statistics as to how fast it can fly, how far it can go, fuel consumption, and so on. Then I have a Flight Class which is all the details about the flight: Distance, starting location and time, ending location and time, duration, and so on.

But I realized that each airplane has multiple flights, so why not put all the flight data into the airplane class? Although how do i put a class INTO another class so i can call something like this:

Player1.Airplane5.Flight6.duration = 5 hours

Ive somewhat done it with the airplane class, but when i go to save the information (listing everything out into a text document), all it gives me is the Hex location of the data and not the actual strings.

class Player (object):#Player Class to define variables
    '''Player class to define variables'''

    def __init__ (self, stock = 0, bank = 200000, fuel = 0, total_flights = 0, total_pax = 0):
        self.stock = stock
        self.bank = bank
        self.fuel = fuel
        self.total_flights = total_flights
        self.total_pax = total_pax
        self.Airplanes = Airplanes
        self.flight_list = flight_list

Is there a way to put a class inside a class? or will i need to make one super Player class which handles all the information which im using other classes for?

I think you are confusing objects and classes. A class inside a class looks like this:

class Foo(object):
    class Bar(object):
        pass

>>> foo = Foo()
>>> bar = Foo.Bar()

But it doesn’t look to me like that’s what you want. Perhaps you are after a simple containment hierarchy:

class Player(object):
    def __init__(self, ... airplanes ...) # airplanes is a list of Airplane objects
        ...
        self.airplanes = airplanes
        ...

class Airplane(object):
    def __init__(self, ... flights ...) # flights is a list of Flight objects
        ...
        self.flights = flights
        ...

class Flight(object):
    def __init__(self, ... duration ...)
        ...
        self.duration = duration
        ...

Then you can build and use the objects thus:

player = Player(...[
    Airplane(... [
        Flight(...duration=10...),
        Flight(...duration=15...),
        ] ... ),
    Airplane(...[
        Flight(...duration=20...),
        Flight(...duration=11...),
        Flight(...duration=25...),
        ]...),
    ])

player.airplanes[5].flights[6].duration = 5
