There are a number of ways to reorganise the data for the exclusive use of your
script without affecting the original data. Is there a reason you can't or not
allowed to do this?
Regardless, here's some code that might make things a little easier. It
operates on each balancer on the fly, reduces the number of for loops, and
eliminates worries about where the tags are placed within the list.
from operator import itemgetter
alist = \
[
[
{u'Value': 'shibboleth-prd', u'Key': 'Name'},
{u'Value': 'kvmu', u'Key': 'Billing'},
{u'Value': '20179204-181622543367489', u'Key': 'Resource_group_id'}
],
[
{u'Value': '20172857-152037106154311', u'Key': 'Resource_group_id'},
{u'Value': 'shibboleth-tst', u'Key': 'Name'}
]
]
# Problem:
# for all resource group id tags that equal '20172857-152037106154311':
# print its name tag (eg, "shibboleth-prd-alb")
# create a container (dict) of tags for each balancer on the fly
for balancer in alist:
tags = dict(map(itemgetter('Key', 'Value'), balancer))
print 'group of tags:', tags
if itemgetter('Resource_group_id')(tags) == '20172857-152037106154311':
print '\tfound resource, resource name:', itemgetter('Name')(tags)
