based on the choices selected in the model...I need to select appropriate region in class view using if_else logic

class GenerateRouterConfig(View):
    def get(self, request, pk, *args, **kwargs):
        router = Router.objects.get(pk=pk)

        AMERICAS = ("1.2.3.4", "10.23.136.1")
        ASIAPAC = ("1.2.3.5", "10.23.136.4")
        EMEA = ("1.2.3.6", "10.23.136.3")
    

        if router.REGIONS[1] == ('AMERICAS','AMERICAS'):
            calculated_public_ip = AMERICAS[0]
            calculated_tunnel_ip = AMERICAS[1]
        elif router.REGIONS[2] == ('ASIA','ASIA'):
            calculated_public_ip = ASIAPAC[0]
            calculated_tunnel_ip = ASIAPAC[1]
        elif router.REGIONS[0] == ('EUROPE','EUROPE'):
            calculated_public_ip = EMEA[0]
            calculated_tunnel_ip = EMEA[1]

        print(calculated_public_ip)
        print(calculated_tunnel_ip)



Models..
class Router(models.Model):
    AsiaPac = 'ASIA'
    Americas = 'AMERICAS'
    EMEA = 'EUROPE'

    REGIONS = [
        (EMEA, 'EUROPE'),
        (Americas, 'AMERICAS'),
        (AsiaPac, 'ASIA'),
    ]
    region = models.CharField(
        max_length=8,
        choices=REGIONS,
        default=Americas,
    )

Any hints? Based on the logic I used its not working..... Based on the if else logic I need to select the appropriate region tuples with calculated tunnel and public ip address.
