Python – parsing and updating json

August 24, 2022

I’m able to load and parse a json file with Python by referring to list items by name. My users.json data file:

{
    "joe": {
        "secret": "abc123.321def"
    },
    "sarah": {
        "secret": "led789.321plo"
    },
    "dave": {
        "secret": "ghi532.765dlmn"
    }
}

My code – to output the ‘secret’ value associated with a specific user (e.g. Dave):

import json

with open('users_sample.json') as f:
  users = json.load(f)
  # f.close()

print(users['dave']['secret'])

This outputs Dave’s secret:

ghi532.765dlmn

That’s easy enough when I can predict or know the user names, but how do I iterate through each user in the users.json file and output each user’s ‘secret’ value?

Thanks in advance!

>Solution :

Iterate the dictionary using a for loop

code that works:

import json

with open('users_sample.json') as f:
  users = json.load(f)

for user in users:
    print(f"user name: {user} secret: {users[user]['secret']}")
