class Application:
    class Moon:
        def __init__(self, name):
            self.name = name
        def __repr__(self):
            "added this to pretty up the printing of a.moons"
            return "Moon(%s)"%self.name

    def __init__(self):
        self.moons = []
        names = ["Io", "Europa", "Ganymeade"]
        for name in names:
            # took Moon(name) out of the setattr()  because we'll be
            # using it again in moons.append. Also used self.Moon
            # because Moon alone raises a NameError
            moon = self.Moon(name)
            setattr(self, name, moon)
            self.moons.append(moon)

a = Application()
print a.moons

# output
[Moon(Io), Moon(Europa), Moon(Ganymeade)]
