如何使用python获取json子类

Question

i have the following json file, the "ticket" python variable contains the "data" part:

{
"date": "139096543" 
"data": [
    {
    "author": {
                "title": "User",
                "champion": false,
                "canonical_name": "tahlia_moffitt",
                "id": 6944932
    },
    "is_spam": false,
    "me_too_count": 2,
    "status": "complete"
    }
]
}

I used the following python script to get the data for example from "status":

'status': ticket.get('status') or 'NoStatus'

But i need the data from the author subclass. I tried as:

'title': ticket.get('author.title') or 'NoTitle'

and

'title': ticket.get('author[title]') or 'NoTitle'

too, but they didnt work for me. Can anybody propose a solution for me?

Answer 1

Try this construction:

'title': ticket.get('author',{}).get(title', 'NoTitle')

Construction

get(title', 'NoTitle')

Will return value if present, if not will return second value.
