Return value of key from dictionary nested in a list Python-CodePudding

I have the following variable in my python script:

response = {"tasks": [{"attachments": [{"id": "id123xyz", "type": "ElasticNetworkInterface", "status": "PRECREATED", "details": [{"name": "john doe"}] }]}]}

I am simply trying to return the value of status. However, I'm unable to do so.

CodePudding user response：

You need to index into each dictionary and list that the status is inside.

You can do the following:

# Prints "PRECREATED"
print(response["tasks"][0]["attachments"][0]["status"])

CodePudding user response：

you need to access the dictionary and the list that is inside:

status = response['tasks'][0]['attachments'][0]['status']

#output
'PRECREATED'

CodePudding user response：

In order to retrieve the status, you can do this

response['tasks'][0]['attachments'][0]['status']

If you would like to extract to dictionary or array of id and status then we can do:

dict([(attachment['id'], attachment['status']) for task in response['tasks'] for attachment in task['attachments']])

returns:
{'id123xyz': 'PRECREATED'}
