How to iterate list python

Question

i have a file like this:

{"user1": {"Login": "Bob", "Secret": "passkey1"}}
{"user2": {"Login": "John", "Secret": "passkey2"}}

with open('users') as data_file:    
   data = [json.loads(line) for line in data_file]

How i can iterate on user1,2 etc to get they 'Secret'? Users just an example

Answer 1

You can try using the following:

import json

{"user1": {"Login": "Bob", "Secret": "passkey1"}}
{"user2": {"Login": "John", "Secret": "passkey2"}}

with open('users.txt') as data_file:    
    data = [json.loads(line) for line in data_file]

for line in data:
    print(line.get(list(line.keys())[0]).get("Secret"))

This will work as long as the format of the dictionary is consistent, but what I mean you have one user per dictionary.

Answer 2

You can try

with open('users') as data_file:    
  for line in data_file:
      for k, v in json.loads(line).items():
          print(v['Secret'])

Output

passkey1
passkey2

This code will create for each line a dictionary and then you can extract the 'Secret' value from each one.

Answer 3

with open('users.txt') as data_file:    
   data = [list(json.loads(line).values())[0]['Secret'] for line in data_file]
print(data)

['passkey1', 'passkey2']

This is what my file looked like

{"user1": {"Login": "Bob", "Secret": "passkey1"}}
{"user2": {"Login": "John", "Secret": "passkey2"}}
