Hi Peter,

Could you please explain what i am doing wrong?  I did inspected the
"get_all_security_groups()" object using dir and i do need the get_data
function for this to work...as i have to parse the output...just getting
the rule and grants does not work...as it comes with extra verbiage that i
do NOT need in my dictionary...see below...

>>> for sg in sgs:
    for rule in sg.rules:
        print sg, sg.id, rule, rule.grants


SecurityGroup:wordpress-app-SG sg-99c4befc IPPermissions:-1(None-None)
[sg-e632d982-995635159130]
SecurityGroup:wordpress-app-SG sg-99c4befc IPPermissions:tcp(22-22) [
67.184.225.222/32]
SecurityGroup:wordpress-app-SG sg-99c4befc IPPermissions:tcp(1024-65535) [
10.0.2.10/32]
SecurityGroup:wordpress-app-SG sg-99c4befc IPPermissions:tcp(80-80) [
24.12.30.198/32]
SecurityGroup:wordpress-app-SG sg-99c4befc IPPermissions:udp(138-138) [
10.0.2.10/32]
SecurityGroup:wordpress-app-SG sg-99c4befc IPPermissions:udp(53-53) [
24.12.30.198/32]
SecurityGroup:wordpress-app-SG sg-99c4befc IPPermissions:tcp(30015-30015) [
0.0.0.0/0]
SecurityGroup:wordpress-app-SG sg-99c4befc IPPermissions:icmp(-1--1) [
10.0.2.10/32]
>>>

i was able to create a list(and nested dictionary) using below... i am open
to making this better if there is a way...

And please accept my apology(in case i am not following certain things) as
i am very new to python...

>>> mylist = []
>>>
>>> for sg in sgs:
    for rule in sg.rules:
        st = sg, sg.id, "inbound:", rule, " source:", rule.grants
        # without the below, we get a comman(,)
        s = str(st).replace(","," ")
        #print s
        jt = get_data(s)
        mylist.append(jt)


>>> mylist
[{'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'}]
