Delete Routing Tables Boto3

Doylers

Hey so what im trying to do is destroy everything to do with my VPC, I get this error

botocore.exceptions.ClientError: An error occurred (DependencyViolation) when calling the DeleteVpc operation: The vpc 'vpc-fb30b29d' has dependencies and cannot be deleted.

I'm pretty sure this error is because my routing tables are not being destroyed, the code is:

for rt in vpc.route_tables.all():
        for rta in rt.associations:
            if not rta.main:
                rta.delete()
    print('Routing Tables Done')

But I really dislike this version since its so blunt, I want to delete by associated VPC. All my tables have the VPC Tag populated vpc-fb30b29d | JtR-Cloud so I would like to specify "VPC_ID + | JtR-Cloud" and loop until they are gone. But I'm lost for how the hell to do this, anyone any ideas?

Answering my own question:

Order does matter, delete in this order:
All instances to remove public IP's
Detach gateway
Subnets
Route table
Endpoints
Security Groups
Network Interfaces
Vpc itself

Code to delete route tables and any associations below:

rtl = vpc.route_tables.all()
    count = sum(1 for _ in rtl)
    while count > 1:

     #delete all route table associations
        for rt in rtl:
            for rta in rt.associations:
                if not rta.main:
                    print("Deleting route table associations")
                    rta.delete()

            for r in rt.routes:
                try:
                    x = r.delete()
                   #  print(x)
                except:
                    pass
            try:
                rt.delete()
            except:
                pass
                 
        rtl = vpc.route_tables.all()
        count = sum(1 for _ in rtl)

I'd recommend looking into either Terraform or Cloudformation to manage AWS resources. It makes life a lot easier compared to using the SDKs - unless you have a specific reason to use Boto.
