从Inner类的实例访问外部类属性

public class Outer {
    private int value;

    public class Inner {
        public void accessOuterValue() {
            System.out.println("Outer value: " + value);
        }
    }
}

Outer outer = new Outer();
Outer.Inner inner = outer.new Inner();
inner.accessOuterValue();

class Outer:
    def __init__(self):
        self.value = 42

    class Inner:
        def access_outer_value(self, outer):
            print("Outer value:", outer.value)

outer = Outer()
inner = Outer.Inner()
inner.access_outer_value(outer)
