I was able to solve the above problem i listed with the following...please
let me know if that is the correct way of doing this...or i am way off?

>>> for sg in sgs:
    for rule in sg.rules:
        st = sg, sg.id, "inbound:", rule, " source:", rule.grants
        s = str(st).replace(","," ")
        #print s
        get_data(s)


{'cidr': 'sg-e632d982-995635159130', 'port': 'None', 'proto': '1'}
{'cidr': '67.184.225.222/32', 'port': '22', 'proto': 'tcp'}
{'cidr': '10.0.2.10/32', 'port': '1024', 'proto': 'tcp'}
{'cidr': '24.12.30.198/32', 'port': '80', 'proto': 'tcp'}
{'cidr': '10.0.2.10/32', 'port': '138', 'proto': 'udp'}
{'cidr': '24.12.30.198/32', 'port': '53', 'proto': 'udp'}
{'cidr': '0.0.0.0/0', 'port': '30015', 'proto': 'tcp'}
{'cidr': '10.0.2.10/32', 'port': '', 'proto': 'icmp'}
