Solve the following python programming problem given the following code:
@ base.skip_without_vpc () 
def test_tag_subnet(self) : 
    cidr = '10.1.0.0/16' 
    data = self.client.create_vpc (CidrBlock = cidr) 
    vpc_id = data ['Vpc'] ['VpcId'] 
    dv_clean = self.addResourceCleanUp (self.client.delete_vpc, VpcId = vpc_id) 
    cidr = '10.1.0.0/24' 
    data = self.client.create_subnet (VpcId = vpc_id, CidrBlock = cidr) 
    subnet_id = data ['Subnet'] ['SubnetId'] 
    res_clean = self.addResourceCleanUp (self.client.delete_subnet, SubnetId = subnet_id) 
    def describe_func(* args, **kwargs) : 
        data = self.client.describe_subnets (* args, ** kwargs) 
        self.assertEqual (1, len (data ['Subnets'])) 
        self.assertEqual (subnet_id, data ['Subnets'] [0] ['SubnetId']) 
self._test_tag_resource (subnet_id, 'subnet', describe_func) 
    self.client.delete_subnet (SubnetId = subnet_id) 
    self.cancelResourceCleanUp (res_clean) 
    self.get_subnet_waiter ().wait_delete (subnet_id) 
    self.client.delete_vpc (VpcId = vpc_id) 
    self.cancelResourceCleanUp (dv_clean) 
    self.get_vpc_waiter ().wait_delete (subnet_id) 

    
    

    Fix the buggy line: self.get_vpc_waiter ().wait_delete (subnet_id)

#Here is Python program to fix the buggy line: self.

self.get_vpc_waiter ().wait_delete (vpc_id)
