Python script for deleting VM using Nova API

This is sample python script that delete virtual machines, keys and security groups where security group has a same name as keypair

Print all object attributes in python

In case of lack of documentation for some API you may need, for example, list of attributes for some object. You can do that using:

from pprint import pprint

pprint (vars(myobject))

or...

pprint (dir(obj))

or....

import inspect
inspect.getmembers(obj, predicate=inspect.ismethod)
