Iterate thru response and get a value via Python

I am trying to get a specific value from the output below. I am trying to get the value for "package_path". I am trying to find the best way to do this. I tried iteritems() but it does not seem to provide the proper value output. Is there another way for me to do this?.. Thanks..

[{"name": "ZONE", "value": "zone01"}, 
 {"name": "VPCNetworkCIDRs", "value": "192.168.30.0/24"}, 
 {"name": "DEPLOYMENT_ENVIRONMENT", "value": "AWS"}, 
 {"name": "parameters_json", "value": "s3://my_folder/zone01/zone01.json"}, 
 {"name": "REGION", "value": "us-east-1"}, 
 {"name": "SECTOR", "value": ""}, 
 {"name": "package_path", "value": "s3://my_bucket/packages/my_app.1.0.2.0.pkg"}, 
 {"name": "component_type", "value": "WebApplication"}, 
 {"name": "PROFILE", "value": "dev"}]

You can use list comprehension.

[arg['value'] for arg in my_list if arg['name'] == 'package_path']

Consider reformatting your data structure into a single dict. For example, using:

data = dict((item['name'], item['value']) for item in items)

Then:

print(data['package_path'])

will give you what you need, and similar for other items.

Since what you have is a list of dictionaries, you must iterate over their name attributes to find the one that you want.

my_list = [{"name": "ZONE", "value": "zone01"}, {"name": "VPCNetworkCIDRs", "value": "192.168.30.0/24"},
 {"name": "DEPLOYMENT_ENVIRONMENT", "value": "AWS"},
 {"name": "parameters_json", "value": "s3://my_folder/zone01/zone01.json"}, {"name": "REGION", "value": "us-east-1"},
 {"name": "SECTOR", "value": ""}, {"name": "package_path", "value": "s3://my_bucket/packages/my_app.1.0.2.0.pkg"},
 {"name": "component_type", "value": "WebApplication"}, {"name": "PROFILE", "value": "dev"}]



package_path = None

# For each name/value pair in my_list...
for name_value in my_list:
    # If the name attribute is package_path, we found it
    if name_value['name'] == 'package_path':
        package_path = name_value['value']  # Store our variable
        break # Exit the loop

if package_path is None:
    print('Package path not found :(')
else:
    print(package_path)  # s3://my_bucket/packages/my_app.1.0.2.0.pkg
