I am trying to find the owner login, owner key, license key, license name for all the repositories which were created_at or after ‘2013-06-04’ from the https://api.github.com/users/mralexgray/repos.

This is using nested list but unable to find out the result: My code is given below:

import requests
import json
url = 'https://api.github.com/users/mralexgray/repos'

content = requests.get(url).content

j = json.loads(content)    
#print(j)

for each in j['owner']['license']:
    print (each ['login']['id'])

I am getting an error:

Traceback (most recent call last):File "<string>", line 11, in <module>
TypeError: list indices must be integers or slices, not str

Not sure how to resolve this issue to findout the key values and parameters. Need help for this.

The structure of the response j is:

[
    {
        "owner": {
            "login": "something",
            "id": 12345
        }
        "license": None,
        "created_at": "2012-10-06T16:37:39Z"
    },
    {
        "owner": {
            "login": "another",
            "id": 6789
        }
        "license": None,
        "created_at": "2014-02-12T11:12:13Z"
    }
]

• Accessing j['owner'] is incorrect because j is a list. What you want is the dictionary inside an item in the list such as j[0]['owner'].
• Accessing j[0]['owner']['license'] is also incorrect because "license" is not a key of the "owner" dictionary. Instead, it is a key of the outer dictionary j[0]['license'].
• Accessing each['login']['id'] is also incorrect because the field "login" is a string, not a dictionary. Instead it is another key in the same dictionary j[0]['owner']['login'] alongside j[0]['owner']['id'].

With the structure I pasted above as reference, you can try this instead:

import json
import requests

url = 'https://api.github.com/users/mralexgray/repos'
content = requests.get(url).content
j = json.loads(content)

for each in j:
    print(each["owner"]['login'], each['owner']['id'], each['license'], each["created_at"])

If you wish to filter the results by the created_at field:

for each in filter(lambda data: data["created_at"] >= "2013-06-04", j):
    print(each["owner"]['login'], each['owner']['id'], each['license'], each["created_at"])

CodePudding user response：

j is an array, so you cannot access owner in it. I guess you'd want more something like:

for each in j:
    ...

Edit: You could even extract all the ids in a quite straightforward way:

ids = [x['owner']['id'] for x in j]

CodePudding user response：

In your code j is list you need iterate over it like below:

import requests
import json
url = 'https://api.github.com/users/mralexgray/repos'

content = requests.get(url).content

j = json.loads(content)    

for i in j:
    print((i['owner']['id']))
