"Error 'ResourceSummaryCollection' object is not subscriptable" OCI PythonSDK - python-3.x

Question

I have python script that queries OCI Compute Instances with a defined tag and value of test and will take the results and stop any instance with those tags. I am expecting the query to return the result as a json object of according to this:
https://docs.oracle.com/en-us/iaas/Content/Search/Tasks/queryingresources.htm
However whenever I take the result and apply it to a variable I get the following error:
"Error 'ResourceSummaryCollection' object is not subscriptable"
I noticed that the query response is not returning as a json object. It is returning as a list.
Update:
This is the error I am getting after updating my script: "Error 'list' object has no attribute 'identifier'". I was expecting the query to return as a json object. When I try to convert the list into a json object via the json dumps method I get object is not serializable. Bottom line is, how do I pass the OCID "Identifier" from the query?
My function:
def do(signer):
print("Searching for untagged instance", flush=True)
# results = ""
# message = ""
# resp = ""
try:
search_client = oci.resource_search.ResourceSearchClient(config={}, signer=signer)
print("Search client initialized",flush=True)
PredefinedTag = "apps"
key= "test"
value= "test"
structured_search = oci.resource_search.models.StructuredSearchDetails(
query="query instance resources where (definedTags.namespace = '{}' && definedTags.key = '{}' && definedTags.value = '{}')".format(PredefinedTag,key,value),
type='Structured',
matching_context_type=oci.resource_search.models.SearchDetails.MATCHING_CONTEXT_TYPE_NONE)
print("Step1",flush=True)
#old
results = search_client.search_resources(structured_search).data
# print(results.items)
# print(results.items.identifier)
# print(results['items'][0]['identifier'])
print("Step2",flush=True)
instanceId = results(results.items.identifier)
# instanceId = results['items'][0]['identifier']
print("Step3",flush=True)
resp = perform_action(signer, instanceId , 'STOP')
print("Step4",flush=True)
except oci.exceptions.ServiceError as e:
print('RQS Search failed with Service Error: {0}'.format(e),flush=True)
raise
except oci.exceptions.RequestException as e:
print('RQS Search failed w/ a Request exception. {0}'.format(e),flush=True)
raise
return resp

Was able to reference the response from the query:
def do(signer):
print("Searching for untagged instance", flush=True)
try:
search_client = oci.resource_search.ResourceSearchClient(config={}, signer=signer)
print("Search client initialized",flush=True)
PredefinedTag = "apps"
key= "test"
value= "test"
structured_search = oci.resource_search.models.StructuredSearchDetails(
query="query instance resources where (definedTags.namespace = '{}' && definedTags.key = '{}' && definedTags.value = '{}')".format(PredefinedTag,key,value),
type='Structured',
matching_context_type=oci.resource_search.models.SearchDetails.MATCHING_CONTEXT_TYPE_NONE)
print("Step1",flush=True)
results = search_client.search_resources(structured_search)
for result in results.data.items:
print(result.identifier + " has availability tag checking status")
print(result.identifier + " status is " + result.lifecycle_state)
instanceId = result.identifier
resp = perform_action(signer, instanceId , 'START')
except oci.exceptions.ServiceError as e:
print('RQS Search failed with Service Error: {0}'.format(e),flush=True)
raise
except oci.exceptions.RequestException as e:
print('RQS Search failed w/ a Request exception. {0}'.format(e),flush=True)
raise
return resp
