两条辅助路线相互操作路由

以下是一个示例代码，展示了两条辅助路线相互操作路由的解决方法：

class Route:
    def __init__(self, name):
        self.name = name
        self.next_route = None
        self.alt_route = None

    def set_next_route(self, next_route):
        self.next_route = next_route
        
    def set_alt_route(self, alt_route):
        self.alt_route = alt_route

    def get_next_route(self):
        return self.next_route
    
    def get_alt_route(self):
        return self.alt_route


# 创建路由对象
route_a = Route("A")
route_b = Route("B")
route_c = Route("C")
route_d = Route("D")

# 设置相互操作的辅助路线
route_a.set_next_route(route_b)
route_b.set_next_route(route_c)
route_c.set_next_route(route_d)
route_d.set_next_route(route_a)

route_a.set_alt_route(route_c)
route_b.set_alt_route(route_d)
route_c.set_alt_route(route_a)
route_d.set_alt_route(route_b)

# 测试
print("Route A's next route:", route_a.get_next_route().name)
print("Route A's alt route:", route_a.get_alt_route().name)

print("Route B's next route:", route_b.get_next_route().name)
print("Route B's alt route:", route_b.get_alt_route().name)

print("Route C's next route:", route_c.get_next_route().name)
print("Route C's alt route:", route_c.get_alt_route().name)

print("Route D's next route:", route_d.get_next_route().name)
print("Route D's alt route:", route_d.get_alt_route().name)

输出结果为：

Route A's next route: B
Route A's alt route: C
Route B's next route: C
Route B's alt route: D
Route C's next route: D
Route C's alt route: A
Route D's next route: A
Route D's alt route: B

在这个示例中，创建了4个路由对象（A、B、C、D），通过调用set_next_route和set_alt_route方法，将它们相互连接起来。然后，通过调用get_next_route和get_alt_route方法，可以获取到每个路由对象的下一条辅助路线和备用辅助路线。

这样，每个路由对象都有两条辅助路线，可以在需要时进行切换和操作。
