How to get the Key Pair value from a json file?

Question

data = "[{"id":"abc, "content":"Bye", "child": [{"id":"dsd", "parent id": "abc", "content": "dds"}]}, {"id": xcv, "content": "hello"}]"

   with open("data.json","w") as f:
        json.dump(data, f)

    # reads it back
    with open("data.json","r") as f:
        parsed_json = json.load(f)

    for e in parsed_json:
        print (e["content"])

I would like to extract Bye and hello but i stumble upon this error. Was wondering how to loop through

Don't use json.dump to write a string to a file. Use it to write a data structure (list, dictionary, etc.) to a file.

So, don't put the original value for your data variable inside quotes.

Also, you're missing some of the quotes in the data ( abc is missing the closing quote, and xcv is missing both quotes).

import json

data = [{"id":"abc", "content":"Bye", "child": [{"id":"dsd", "parent id":"abc", "content":"dds"}]}, 
        {"id":"xcv", "content":"hello"}]

with open("data.json","w") as f:
        json.dump(data, f)

# reads it back
with open("data.json","r") as f:
    parsed_json = json.load(f)

for e in parsed_json:
    print (e["content"])
