Python 解析 API 响应 Json 主体嵌套数据

Question

I am trying to call get api using python and fetch the covid vaccine details and storing into one proper formate. Into the same I am able to fetch CENTER data like "center_id,name, address,state_name" but I am not able to fetch the SESSIONS data as below

Below is how I am parsing the JSON response.

dataJ = json.loads(r.text)
for i in range(len(dataJ['centers'])):
    center = dataJ['centers'][i]['name']
    address = dataJ['centers'][i]['address']
    state = dataJ['centers'][i]['state_name']
    district = dataJ['centers'][i]['district_name']
    pin = dataJ['centers'][i]['pincode']
    date =dataJ['centers'][i]['date']
    print(center,"-",address,"-",state,"-",district,"-",pin,"-",date)

It gives me error as below

date =dataJ['centers'][i]['date'] KeyError: 'date'

Can someone please help me in this regard?

You need to do something similar to the sessions array, just like you did with the centers array. See the NEW marked section below:

dataJ = json.loads(r.text)
for i in range(len(dataJ['centers'])):
    center = dataJ['centers'][i]['name']
    address = dataJ['centers'][i]['address']
    state = dataJ['centers'][i]['state_name']
    district = dataJ['centers'][i]['district_name']
    pin = dataJ['centers'][i]['pincode']
    date =dataJ['centers'][i]['date']
    print(center,"-",address,"-",state,"-",district,"-",pin,"-",date)

    # NEW: now process each session like you want
    for j in range(len(dataJ['centers'][i]['sessions'])):
        # do what you want with the session here:
        # it's also easier to use variables rather than reproducing the entire index sequence repeatedly
        session = dataJ['centers'][i]['sessions'][j]
        session_id = session['session_id']
        # ...
