如何从此Json数据中获取特定数据？

Question

I have the following JSON data

    {
    "results": [
        {
            "alternatives": [
                {
                    "confidence": 0.6,
                    "transcript": "state radio "
                }
            ],
            "final": true
        },
        {
            "alternatives": [
                {
                    "confidence": 0.77,
                    "transcript": "tomorrow I'm headed to mine nine 
    consecutive big con I'm finna old tomorrow I've got may meet and greet 
    with whoever's dumb enough to line up "
                }
            ],
            "final": true

If I try data["results"] , it works and I get everything inside "results".

But if I try data["alternatives"] , it doesn't work.

I want to get the text in "transcript", how can I get that?

Answer 1

"transcripts" is not a direct child of data . It is, instead, the child of element "alternatives" , which is a child of each element of the list "results" , which is, in turn, the direct child of data . So, to get your contents of transcript as a list, do:

transcripts = [r["alternatives"]["transcript"] for r in data["results"]]

Answer 2

To access alternatives,

data['results'][0]['alternatives']['transcript]

change the index 0,1,2,3 ... according to which transcript data you need to extract.

Answer 3

You can get the expected result by using the code:

import json
d='''
    {
    "results": [
        {
            "alternatives": [
                {
                    "confidence": 0.6,
                    "transcript": "state radio "
                }
            ],
            "final": true
        },
        {
            "alternatives": [
                {
                    "confidence": 0.77,
                    "transcript": "tomorrow I'm headed to mine nine consecutive big con I'm finna old tomorrow I've got may meet and greet with whoever's dumb enough to line up "
                }
            ],
            "final": true
        }
    ]}
'''
data = json.loads(d)
for i in range(len(data['results'])):
    transcript=data['results'][i]['alternatives'][0]['transcript']
    print(transcript)
