Function to return all related data from json list using any given key

Question

I have the following json data about experts.

result={
        "experts":[
  {
    "thumbnail": "https://scholar.googleusercontent.com/citations?view_op=small_photo&user=JicYPdAAAAAJ&citpid=2",

    ]
  },
  {
    "thumbnail": "https://scholar.googleusercontent.com/citations?view_op=small_photo&user=kukA0LcAAAAJ&citpid=3",
    "name": "Yoshua Bengio",

      }
    ]
  }
        ]
    }

Given an input of "author_id" I want to get all the data related to that "author_id".For example if I give the input "JicYPdAAAJ" i want to get the thumbnail,name,email,link,affilations,etc and all the related with that author id from the list of Json data.In this case all the related data about Geoffrey Hinton will be returned.
How do I write a function to achieve this?So far I tried using key value matching but the logic does not seem to work.
Hope somebody helps

Answer 1

Iterate over the list and find the author id:

def get_expert_details(author_id: str) -> dict:
    for expert in result['experts']:
        if expert['author_id'] == author_id:
            return expert

Answer 2

You can just iterate over the all authors and check if ‘author_id’ is the same as you provided. example:

SEARCH_ID = 'kukA0LcAAAAJ'
for enum, expert in enumerate(result['experts']):
    if result['experts'][enum]['author_id'] == SEARCH_ID:
        print(result['experts'][enum]['name'])  # PRINT key NAME

which returns
Yoshua Bengio
you can edit this code to print whatever data you want.

Answer 3

You can use list comprehension – https://docs.python.org/3/tutorial/datastructures.html#list-comprehensions

answer = [expression for item in iterable if condition == True]

In your case:

answer = [x for x in result["experts"] if x["author_id"] == "JicYPdAAAAAJ"]

Note – this will return a list with the data you are looking for.

Also you have an error in your question. The id mentioned in the text, "JicYPdAAAJ", is different to the id in your data, "JicYPdAAAAAJ"
