python - How to access the dict value? -

i have response syntax of type dict:

{     'stoppinginstances': [         {             'instanceid': 'string',             'currentstate': {                 'code': 123,                 'name': 'pending'|'running'|'shutting-down'|'terminated'|'stopping'|'stopped'             },             'previousstate': {                 'code': 123,                 'name': 'pending'|'running'|'shutting-down'|'terminated'|'stopping'|'stopped'             }         },     ] } 

now if need check if currentstate stopping how so?

print "stopping instance now",response['stoppinginstances']  instance in response['stoppinginstances']:     if instance['currentstate']['name'] == "stopping":         print "still stooping"      if instance['currentstate']['name'] == "stopped":         print "instance stopped" print "now starting instance" response_new = client.start_instances(instanceids=[instance_id]) start_instance in response_new['startinginstances']:     if start_instance['currentstate']['name'] == "running":         print "instance , running"     else:         print "some error occured!!" 

your data contains list enclosing outer dict values, , not simple nested dictionaries suppose. need index list, access nested dict values via keys:

response['stoppinginstances'][0]['currentstate']['name'] #                             ^ 

and in if block:

if response['stoppinginstances'][0]['currentstate']['name'] == "stopped":      print "instance stopped"
