   from boto.vpc import VPCConnection import boto.ec2 from boto.ec2 import EC2Connection

   
   

   
   ec2_conn = EC2Connection()
   ec2s = ec2_conn.get_all_instances()
   
   region = boto.ec2.regions()
   print region
   print region[0]
   vpc_conn = VPCConnection()
   
   vpcs = vpc_conn.get_all_vpcs()
   for vpc in vpcs:
       print" %35s " %vpc
   
       subnets = vpc_conn.get_all_subnets(filters={ 'vpc_id': vpc.id })
       for subnet in subnets:
           print" %45s " %subnet.id
           '''print" %45s " %subnet.availability_zone
           print" %45s " %subnet.cidr_block
           print '' '''
   
       route_tables = vpc_conn.get_all_route_tables(filters={ 'vpc_id': vpc.id })
       for route in route_tables:
           print" %55s " %route
           print ''
   
       acls = vpc_conn.get_all_network_acls(filters={ 'vpc_id': vpc.id })
       for acl in acls:

       typ = vpc_conn.get_all_internet_gateways(filters={'attachment.vpc-id':
   
   

   
   

   vpc.id}) for i in typ: print" %55s " %i

   
   

   
       typ3 = vpc_conn.get_all_security_groups(filters={'vpc_id': vpc.id})
       for t3 in typ3:
           print" %55s " %t3
