Accessing nested values in JSON data from Twitch API

Question

I am using the code:

getSource = requests.get("https://api.twitch.tv/kraken/streams")
text = json.loads(getSource.text)
print text["streams"]["_links"]["_self"]

text is a dictionary that I get by calling json.loads. I then try to get the nested values, eventually trying to get the url but this error shows up:

Traceback (most recent call last):
  File "Twitch Strim.py", line 11, in <module>
    print text["streams"]["_links"]["_self"]
TypeError: list indices must be integers, not str

How can I correct this?

Answer 1

You are accessing the json data wrong, the correct way of accessing this would be:

print text["streams"][0]["_links"]["self"]

Full code:

>>> import requests
>>> import json
>>> getSource = requests.get("https://api.twitch.tv/kraken/streams")
>>> text = json.loads(getSource.text)
>>> print text["streams"][0]["_links"]["self"]
https://api.twitch.tv/kraken/streams/summit1g
>>> print text["streams"][1]["_links"]["self"]
https://api.twitch.tv/kraken/streams/tsm_theoddone
>>> print text["streams"][2]["_links"]["self"]
https://api.twitch.tv/kraken/streams/reynad27

Note that text["streams"] provides you a list of items (and not a dict), so you will have to access by its index values.

You can check the same using

>>> type(text["streams"])
<type 'list'>
