Python JSON TypeError: list indices must be integers or slices, not str

Question

I am currently trying to parse some data from a get request response and I keep getting this error: "TypeError: list indices must be integers or slices, not str"

it would be great, if anybody could help me out what i am trying to solve. thank you so much in advance.

import requests
import json


class userList(APIView):
    def get(self,request,format=None):

        user_data = []
        url = 'https://reqres.in/api/users?page=1'

        try:
            r = requests.get(url).json()
            user = {
                'id': r['data']['id'],
                'email': r['data']['email']
            }
            user_data.append(user)
            return Response({"user_data":user_data}, status=status.HTTP_200_OK)

{
data:{

0:{
'id'    : 1
'email' :   "[email protected]"
'first_name' :  "George"
'last_name' :   "Bluth"
'avatar' :  "https://s3.amazonaws.com/uifaces/faces/twitter/calebogden/128.jpg"
}

1:{
'id'    : 2
'email' :   "[email protected]"
'first_name' :  "apdas"
'last_name' :   "loanz"
'avatar' :  "https://s3.amazonaws.com/uifaces/faces/twitter/calebogden/128.jpg"
}

2:{
'id'    : 3
'email' :   "[email protected]"
'first_name' :  "joan"
'last_name' :   "homli"
'avatar' :  "https://s3.amazonaws.com/uifaces/faces/twitter/calebogden/128.jpg"
}
}
}

Is data a dictionary of a list? Separate each x[y] into it's own line so you can see which is causing the error, i suspect you need r[0]['data']['id'] — Macattack

What line is flagged in the traceback. (You should include the traceback in your question.) — Steven Rumbalski

Inspect r['data'] and check if it has a list instead of a dict. In a quick look here at your json content I think that the correct is use r['data'][someIndex]['id'] for example. You should be use something like r['data'][0]['id'] — Edy Silva

i am getting one value. Instead of adding [0], is it possible that iterate through results in case there is more than one result. @GeekSilva — satyajit

Try this:

user_data = [{'id': x['id'], 'email': x['email']} for x in r['data']]

Output:

[{'id': 1, 'email': '[email protected]'}, {'id': 2, 'email': '[email protected]'}, {'id': 3, 'email': '[email protected]'}]
